Abstract
The present disclosure relates generally to the field of static dissipative coatings. More specifically, the present disclosure relates to the methods of making static dissipative, preferably non-chromium-containing, coatings comprising carbon nanotubes, the coatings themselves, and structures comprising such coatings.
Claims5
A method for making a mixture for use in making a static dissipative coating comprising the steps of:
- preparing a solution, said solution consisting essentially of multi-walled carbon nanotubes and tert-butyl acetate, said multi-walled carbon nanotubes having a diameter of from about 6 to about 9 nm;
- sonicating the solution a first time;
- adding an epoxy resin to the solution to form a mixture while
- sonicating the mixture a second time;
- and
- maintaining the mixture at a temperature below 120° F.;
- wherein the mixture maintains the multi-walled carbon nanotubes in a dispersion for at least two weeks.

A method for applying a static dissipative coating to a substrate comprising the steps of:
- applying a mixture to the substrate to form the static dissipative coating on the substrate, said mixture comprising a solution,
- said solution consisting essentially of multi-walled carbon nanotubes and tert-butyl acetate, said multi-walled carbon nanotubes having a diameter of from about 6 to about 9 nm,
- an epoxy resin, and a curing agent;
- and
- wherein the coating has a resistivity of from about 5×105 to about 5×109 ohm/square.
