英文摘要	A series of organic-inorganic hybrid thermal control coatings (TCCs) were prepared. The binder was prepared by co-pre-hydrolysis/condensation of tetraethylorthosilicate (TEOS) and siloxane, subsequently mixing with 3-aminopropyltriethoxysilane (APTES) as curing catalyst and ZnO powder as optical pigment. The coatings can be cured at room temperature naturally with low solar absorptance alpha(S) and high thermal emittance epsilon(H). Fourier transform infrared spectroscopy (FT-IR) and gel permeation chromatography (GPC) measurements were carried out to understand the structures of the coatings. FT-IR spectra and GPC analysis results showed that the as-prepared hybrid binder carried lots of active hydroxyls with an appropriate polymerization degree. Thermal gravimetric analyzer (TGA) test showed that as-prepared coatings have high thermal stability at 200 degrees C. alpha(S)/epsilon(H) value could be further reduced by increasing the coating thickness, and optical absorption of the coatings in the infrared wave band could be further reduced by increasing TEOS content. This work provides an effective way to obtain room temperature cured TCCs with low alpha(S)/epsilon(H) value.
