1. INTRODUCTION
Nanofibers are one-dimensional nanomaterials ranging in diameter from hundreds to thousands of
nanometers in the form of fibers. Textile, tissue engineering, pharmaceutical and drug delivery
systems are just a few of the applications for nanofibers. Nanofibers are a type of material that can
also be used for filtration, protective garments, battery separators, and energy storage, among other
things. Carbon Nanofibers are widely used in Antenna designing. [1]
Bi-component fiber spinning, Melt-blowing, template synthesis, phase separation, self-
assembly, drawing and centrifugal spinning are some of the processes used to make nanofiber.
These are the difficult methods for making Nanofibers from a limited number of polymers.
Electrospinning is the most common process for manufacturing Nanofibers from diverse polymers.
Electro-spinning is also called electro-static spinning. In this technique, we produce Nanofibers of
different diameters. Electro-spinning technique is the most effective technique in the generation
of Nanofiber.
The high-performance electrospinning machines are available in international market in
high prices. We are designing and developing a cost-effective electrospinning machine that can be
used at the local or national level. Our design of the electrospinning machine is shown in Figure
(1).

2. OBJECTIVES
1. To design and develop a prototype of an electrospinning machine composed of mechanical
hardware, PCB, Stepper motor (To control the speed of syringe pump), Brushless DC
motor (Collector Drum), GUI (effective control of machine), Arduino based control and to
safely apply an electrical application of high DC voltage between the syringe pump and
collector drum.
2. To calibrate electrospinning machine for reliable performance i.e rotation speed of
collector drum and the syringe flow rate, This objective also includes the calibration and
optimization of the machine by performing nanofabrication using different substrates and
nanofiber materials.
3. LITERATURE REVIEW
In the year 1900, electrospray technology, which began in the late 1890s, was developed into
electrospinning.[2]
To gain a better knowledge of the background to this innovative approach, we
give a comprehensive table (Table 1), detailing the year-by-year development of electrospinning.
Electrospinning is a method of employing electric charges to distort a conical droplet of
polymer Solution pushed from a nozzle tip into ultra-fine fibers. Filter membranes, artificial
organs, biomedical scaffolds, chemically protected garments, nanoelectronics, nanocomposites,
conductive polymeric biosensors, and wound dressing materials could all benefits from
nanometer-sized fibers. [3]
3.1 Electrospinning Process
Electrospinning is a physical method that involves exposing a polymer solution to strong electric
fields in order to produce ultrathin fibers. Figure 2 depicts a schematic illustration of a typical
laboratory electro-spinning setup. A polymer solution is deposited within a syringe that is
horizontally mounted on a digitally controlled pump, allowing for exact control of the solution
flow rate. The polymer solution is then injected through a millimeter-sized metallic needle that is
connected to a high-voltage power source operating in positive DC mode with low current
intensity.

During this time, the majority of papers focused on the use of
electrospun nanofibers as sensors, tissue engineering
materials, chemical warfare stimulant protection, filters,
scaffolds, batteries, and catalysts. In addition, these
microfibers have found use in the medical industry as
medication delivery devices.
For mosquito protection, electrospinning potential is used to
make cloth. The fabric that resulted was found to be helpful in
preventing mosquito bites in tests.

8. 5
At a critical high voltage, the polymer solution droplet at the needle's tip bends and forms a Taylor
cone, which is subsequently ejected as a charged polymer jet (25 kV). The electrical field extends
and accelerates this towards a grounded and oppositely charged collector. The solvent entirely
evaporates as the electro-spinning jet moves through the electrical field, while the entanglements
in the polymer chains prevent it from breaking up. As a result, ultrathin polymer fibers are
deposited on a metallic collector, which is then used to combine the fibers into nonwoven mats. [9]
Electrospun fiber mats with ultra-fine structures, high porosity, a high surface-to-volume
ratio, and customizable morphology are produced using this nonmechanical technique.
Electrospinning is a non-thermal method that encapsulates thermosensitive compounds, which is
important for preserving structure and increasing stability and functionality during food
preparation and storage. [10]

4. PROPOSED METHODOLOGY
In Electro spinning machine there are two major parts:
1. Mechanical Parts
2. Electrical parts
4.1 Proposed Model
We use Arduino and an LM-298 DC Motor Driver to regulate the speed of our collector drum.
We have a variable resistor to control the speed of the collector drum and display the revolutions
per minute of the collector drum on LCD.
We used an Arduino Uno and a stepper motor driver in our syringe pump. The syringe is
driven by a threaded rod linked to our stepper motor. We are using another LCD to display the
speed of the motor in milliliters per hour.

4.2 Hardware
The Hardware of Electro spinning machine include:
4.2.1 Mechanical Parts
Syringe
Sucking and ejecting liquid through a tube with a nozzle and piston or bulb in a narrow stream.
The syringe is an essential component of an electro-spinning machine. The electrically spun
solution is poured into the syringe. The rate at which the polymer solution flows is a significant
parameter. Because the polymer solution takes a certain amount of time to polarize, a syringe pump
with a modest flow rate is preferred. When the flow rate is high, bead fiber with a large diameter
form instead of smooth fiber with a small diameter, which dries quickly once it reaches the
collector. [11]
Base
An electro-spinning machine's foundation is an important component that assures the machine's
stability and protects it from jerks, vibrations, and other accidental vibrations.
Supporting Pillars
Supporting pillars give collector drum and rod a solid basis, ensuring that they stay in place. Our
support is made of plastic, which ensures that the components are securely held in place and
protective.
Collector Drum
In our electrospinning machine collector drum is also an important part. It is made up of steel or
aluminum. The material which is to electrospun is placed on the collector drum and the collector
is grounded. The ionized solution which is emitted from the syringe is deposited on the collector.
The speed of the collector drum effect’s the diameter of the fiber. [12]

11. 8
Nut & Bolts
A nut and bolt are a little flat piece of metal or other material with a threaded hole in it that is used
as a fastener to screw onto a bolt.
Thread Road
Threaded bars, often called studs, are cylindrical bars that have continuous threading at both ends
but no head and fashion tip. They can be used as a U-bolt, anchor bolt, clamp, or hanger, among
other applications. The threaded rod could be threaded all the way down the rod.
Ball Bearings
A bearing is a machine part that decreases friction between moving elements by limiting relative
motion to the desired value.
4.2.2 Electrical Parts
Stepper Motor
An electromagnetic device that converts digital signals into mechanical shaft rotation is known as
a stepper motor. Step motors feature a basic, solid architecture that can work in practically any
environment, as well as a low cost, great durability, high torque at low speeds, and a low cost. To
regulate the speed of the syringe pump, we utilize an Arduino and a stepper motor. We will use
the A4988 stepper motor driver to adjust the syringe pump's speed.
Brushless DC Motor
Brushless DC motors (sometimes referred to as BLDC motors or BL motors) are brushless DC
motors without brushes. The controller controls the synchronous motor speed and torque by
sending current pulses to the motor windings. To control the speed of the collecting drum, we
utilize an Arduino and a DC motor. LM-298N will be used to change the speed of the collection
drum.

12. 9
Figure 2: Process of electrospinning
LM-298N
The L298N Motor Driver is a controller that uses an H-Bridge to control the direction and speed
of up to two DC motors. To run the DC motor, we linked this Module to Arduino. This driver will
be used to control the DC motor's speed.
Arduino Uno
The Arduino Uno microcontroller board uses the ATmega328P CPU. 14 digital input/output pins
(six of which are PWM outputs), six analogue inputs, a 16 MHz quartz crystal, a USB connection,
a power jack, an ICSP header, and reset buttons are all found on this board. An Arduino Uno is
used to control speed and direction of stepper motor and brushless DC motor.
A4988
For ease of usage, the A4988 is a comprehensive micro-stepping motor driver with an integrated
translator. It can operate bipolar stepper motors in full, half, quarter, eighth, and sixteenth phase
modes with an output drive capacity of up to 35V and 2A. This driver is used to regulate the stepper
motor's speed, which controls the syringe's speed.

4.3 Software
Software that we will use are Following
Fusion 360
Fusion 360 is a product design and manufacturing cloud-based 3D modelling, CAD, CAM, CAE,
and PCB software platform. Aesthetics, form, fit, and function are all variables to consider while
designing and engineering anything. The Fusion 360 is being used to create a 3D model of our
electro-spinning machine. This is useful software for determining the stability and size of hardware
models.
Arduino IDE
The software that was used to program the Arduino. Arduino IDE is the name of the software for
Arduino (Integrated Development Environment). It's a text editor with a lot of features that
operates like a notepad. It's used to write code, compile it for error checking, and then upload it to
an Arduino. This software is used to program the Arduino to control the speed of the Stepper and
DC motors.
Proteus
The Proteus Design Set is a proprietary software tool package primarily used for electronic design
automation. The software's major users are electronic design engineers. This software is used to
design the circuit diagram of our electrical circuits in the electrospinning machine, such as the
Arduino connecting to the A4988 driver and the A4988 driver connecting to the Stepper motor.
Processing IDE
Processing is a free graphical library and integrated development environment (IDE) for the
electronic arts, new media art, and visual design communities that teach the fundamentals of
computer programming in a visual setting. This software is used to create the user interface for our
project. This user interface improves the usability and efficiency of our project.
