摘要: A method of forming an electrostatic dissipative composite material includes preparing a mixture comprising a polyamic acid precursor and a non-carbonaceous resistivity modifier. The polyamic acid precursor reacts to form polyamic acid. The method also includes dehydrating the polyamic acid to form polyimide. The polyimide forms a polymer matrix in which the non-carbonaceous resistivity modifier is dispersed.
