Electrical characterization of conducting nanoparticles-polysiloxane composites for a space durable coating

Electrical properties of composites filled with three different fillers were studied in order to elaborate an antistatic cold thermal control coating for space application. The influence of the aspect ratio of filler on pc value was observed. Indeed, p_c in CNTs composites is lower than in spherical particles ITO composites. The surface potential value imposed by the European standard was only reached for high CNTs content sample, but the solar absorptivity is too high for the final use.
