The thin films containing metal oxides semiconductors have excellent properties of visible light transmission and conductivity, which provides promising applications in these fields of materials and energy etc. The traditional vapor deposition method is being replaced by simple rapid deposition method, like printing, due to the high energy cost of traditional deposition method in the preparation of thin films. However, how to prepare the nanoparticles with good dispersibility is a key challenge. In this proposal, we will use the quantum chemistry calculations to design the new metal oxide materials and further adopt novel high-gravity reaction coupled with phase transfer technology to synthesize the designed metal oxides nanoparticles, aiming at achieving the transparent mono-dispersion of metal oxides. By coating the mixture containing metal oxide and organic resin on transparent plastic and glass, we fabricate the isolating infrared thin film, which can act as smart optical window materials for building energy saving. The formation mechanisms of transparent mono-dispersion will be studied in high-gravity environment, which will guide the preparation of the metal oxides nanoparticles dispersed easily in organic coating by high-gravity technology. The effect of composition and structure of nanoparticles, dispersion state of nanoparticles in coating matrix and interfacial reaction mechanism between nanoparticles and matrix on the optical and electrical properties of the nanocomposite will be explored. This proposal would provide theoretical and technical fundaments for the applications of the metal oxide contained thin film as optical window in energy-saving glass.
