Conductive Composite Materials Based on Heat-Resistant Fluorine-Containing Polyamide and Binary Filler

Abstract

Shown here is the possibility of obtaining of current-conducting composite film of the system “binary filler + polymer matrix” where the mix of carbon nanofiber and nickel boride was chosen as the filler at various percentage ratios. Its introduction (up to 80 wt.%) raises deformation strength of composite while heating and give it electric conductivity. The film microstructure is studied by SEM. Electric-physical characteristics viz. volt-amps diagrams as well as R(T) dependence are determined. Temperature coefficient of resistance is established to change while introducing carbon nanofiber.
