Conductive Thermal Control Coating via the Sol-Gel Process
with Electrically Modified Optical Properties
Abstract:
Sol-gel processing has been proved to be a successful route to make
diverse ceramic coatings. In this research, a composite ceramic
coating via the sol gel process has been proposed, with the
transition metal oxides (ZnO, FeTiO3, VO2) spherical partical
particles having the required optical properties for spacecraft
thermal control, and tin oxide (SnO2) matrix provides high
electrical conductivity (up to 103Q-1cm-l) for electrostatic
discharge control. Also, these dispersing materials have
electrically modified optical properties, thus resulting the
optical properties of the coatings being modified electrically.
The conductive thermal coatings are used for the control of the
thermal environment of a spacecraft. If the proposed coating is
successfully fabricated, it will provide a coating with the wide
range of the D optical properties to spacecraft designers. These
coatings can be used in tethered satellites and all other
commercial spacecrafts.
