Synthesis and the Surface Resistivity of Carbon Black Pigment on Black Silicone Thermal Control Coating

Abstract

Thermal control has become more and more important in the development of the spacecraft technology. The thermal control coatings are exposed to electrostatic charges that develop on the external surface of the spacecraft. In this research, the synthesis, the surface resistivity, and the influence of the type, percent of the pigments, and adhesive properties on the coating were studied. The weight fraction of the pigment in coatings fabricated by carbon black with a sponge-like structure are lower compared to coatings fabricated by carbon black with a nonporous structure also, the surface resistance decreased with increasing pigment contents.
