ABSTRACT:
A method and composition which provides both thermal control and electrostatic discharge protection to bodies in the space environment. The composition comprises: a) a chosen polymer or resin that forms a polymer that is an electronic insulator and is suitable for space applications; and b) a selected lithium salt as a dopant wherein said composition, when formed into a film or coating, provides a semiconductive film or coating having a volume resistivity of about 10.sup.6 to 10.sup.11 ohm-centimeter and a value of solar absorptance/total normal emittance within the range of about 0.305 to 0.595. In an alternative embodiment, the composition may optionally include tantalum pentoxide.
