英文摘要	A novel thermochromic sol-gel film has been prepared for the first time through entrapping phosphomolybdic acid into a kind of inorganic-organic matrix co-hydrolyzed from tetraethylorthosilicate and 3-aminopropyltriethoxysilane. The thus-obtained amorphous nanocomposite film was characterized by IR spectra, UV-vis absorption spectra, XRD, TG-DTA, and ESR. Results show that phosphomolybdate polyanions interact with R-NH3+ cations strongly and disperse homogeneously in the sol-gel matrix. The sol-gel film exhibits thermochromic properties. Annealed from 120 to 180degreesC, the transparent film changes from pale-yellow to blue. A possible charge-transfer process has been suggested to explain the thermochromism.
