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).

Electrochemistry Applications: Paints & Coatings

  1. 1. 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
  2. 2. 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). Paints and Coatings Reference 600

ELECTROCHEMICAL TESTING ON FILMS The Ideal Solution Reference 600 Potentiostat for very small capacitance measurements eQCM 10M designed to accurately measure hard and soft materials FlexCell a flat specimen cell that can hold two separate flat electrodes Gamry has the right instrument for your Application
  4. 4. 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. PTC1™ Paint Test Cell
  5. 5. 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.

  6. 6. 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.
