Paints & Coatings

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.

Paints and Coatings

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.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).

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.

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.
