摘要：
Series of novel energy-saving window coatings based on F-Nb-TiO2/SiO2 nanocomposites with superhydrophobic self-cleaning performance were successfully prepared. Surface modification of F-Nb-TiO2 and SiO2 nanoparticles by aminopropyl triethoxy silane and perfluorooctyltriethoxysilane produced hydrophobic powders. With the help of the hierarchical structures of F-Nb-TiO2/SiO2 nanocomposites, superhydrophobic surfaces were obtained. The water contact angle of the composite coatings reached 155.6 degrees. The prepared superhydrophobic coatings shown superior anti-fouling property and good mechanical performance. Furthermore, the composite coating can shield most of solar radiation. The composite coating lowed the air temperature of the simulate house by 11 degrees C in the outdoor thermal experiments. The integration of good solar filtration and exceptional anti-fouling performance makes F-Nb-TiO2/SiO2 coatings suitable candidates for energy-saving window coatings.
