Abstract

Polyurethane (PU) is a multi functional polymer prepared by using more than two types of monomers. The unique properties of PU come from monomers, thus broadening the applicability of PU in many different sectors. Furthermore, the antistatic property of PU coatings can be improved by the addition of conductive fillers into matrix thus broadening its application in the manufacture of electronic products, aerospace systems and daily necessities and so on. The use of electrically conductive metal oxides as fillers makes it possible to reduce the resistivity of polymeric materials and slow down the flow of electric charges. In this study, a novel robust low density anti static polyurethane (APU) coating with Titanium dioxide (TiO2) and graphite as conductive fillers were specially designed for application on polyurethane flexible foam for reusable launch vehicles. For this purpose, the effective parameters on resin performance and surface resistivity of the synthesized coating were investigated and optimized. The surface resistivity of antistatic polyurethane coating containing 20-22 wt% TiO2 and graphite reached 105 Ω/sq and 109Ω/sq respectively.

Keywords: Antistatic Polyurethane (APU) Coating, Conductive Fillers, Titanium Dioxide (TiO₂), Graphite, Surface Resistivity
