Abstract
A spacecraft protected by a coating includes a spacecraft such as a communications satellite has an external surface and a coating on the external surface of the spacecraft. The coating is formed of a binder, and a plurality of pyroelectric/ferroelectric pigment particles, preferably ferroelectric particles, bound together by the binder. Each ferroelectric pigment particle includes a ferroelectric pigment material having a ferroelectric/paraelectric transition. The coating may also include active secondary particles and/or inert particles. The coating may operate in a passive mode or an active mode with the application of a bias voltage to the coating.
