Process for Preparing Conductive Cellulose and
Cotton Using Ionic Liquids

2. Current Problems
• Intrinsic conducting polymers (ICPs) have immense
variety in physical and electronic/conductive
properties
• Polypyrrole (PPy) consist of five membered
heterocyclic rings
– Low resistance, redox properties, environmental stability
• Conductive polymers into nanostructure
– Oxidation process is unsafe and uses harsh chemicals
– Significant degradation in mechanical properties

3. • Novel process fabricating nanostructure conductive
polypyrrolecellulose fiber composites using Ionic
Liquid (IL) solvent
• IL acts as a solvent for the polymerization of pyyrole
and can dissolve as cellulose
– Combination of both properties lead to effectively
impregnate cellulose fibers as well as effectively
polymerize pyrrole
• Resulting in electrically conductive cellulose fiber composites
Technology

4. • Enhancement
– Mechanical and conductive properties
• Fe(III) absorption peaks at 65mg/g around 10 minutes
– Indications of significant improvement compared to other
processing routes
• Increased amounts of nanostructure polypyrrole particles
• Resistance of conductive cellulose fiber composite reduced
significantly with increased pyrrole concentration
• Degradation of strength and stiffness
Advantages
