Due to the overwhelming number of uses for thin films and coatings, a wide variety of testing is available for distinguishing characteristics and analysis. Electrochemical characterization can be done with DC and AC techniques, but the most powerful tool is electrochemical impedance spectroscopy (EIS).

2. In the world of materials research, thin films serve
many different purposes. They can be protective films
to preserve some substrate or building material. They
can be conductive or insulating films that may be used
for devices where directing electron transport is the
goal. They may be membranes designed to pass some
species and block others. They may be designed to
change characteristics under certain conditions.

3. Whether it is corrosion preventing
paint on the Eiffel Tower or Golden
Gate Bridge or an enzyme
monolayer on an electrode, films and
coatings serve critical functions in
science and industry.

5. The PTC1™ Paint Test Cell is a low-cost
sample cell for electrochemical testing of
coated samples. The PTC1 can also be
used to test bare metal samples using
portholes electrochemical sample masks.

6. EIS300 and either DC105 (DC
corrosion) or PHE200 (physical
electrochemistry) software will take care of most
situations. There are other packages that may be
of use to some researchers, like pulse
voltammetry (PV220) for stripping experiments
or electrochemical frequency modulation
(EFM140) for better corrosion trend testing.

7. Gamry Expertise
Gamry published a series of three papers on the “Evaluation
of Organic Coatings with Electrochemical Impedance
Spectroscopy” in JCT CoatingsTech in 2004 and
2005. Along with those articles, we have several applications
notes available for download dealing with EIS and coatings.
Our sales and support staff consists of electrochemists and
engineers with real-world research experience that
understand Paints & Coatings and can get you pointed in the
right direction.
