Abstract
In this paper,firstly,prepare TiO2@SiO2 nanospheres.Subsequently,the vertical deposition method is used to coat the surface of the PV glass TiO2@SiO2 nanocomposite films.Then,through laser particle size analysis,X-ray powder diffraction(XRD)analysis,and infrared spectroscopy analysis to phase analysis is conducted on TiO2@SiO2 nanospheres.Finally,the transmittance and hydrophobicity of TiO2@SiO2 nanocomposite films are studied.The research results show that:1)Adding different amounts of tetrabutyl titanate will have an impact on particle size distribution of TiO2@SiO2 nanospheres.As the amount of tetrabutyl titanate added increases,particle size distribution range of TiO2@SiO2 nanospheres shows a trend of narrowing first and then widening.When adding 3 mL of tetrabutyl titanate,obtained the particle size distribution of TiO2@SiO2 nanospheres is relatively uniform and the shell thickness is appropriate.2)After calcination and annealing,it can effectively improve the crystallization degree of TiO2@SiO2 nanospheres,and the more tetrabutyl titanate added,the better the crystallization degree.3)As the amount of tetrabutyl titanate added increases,the sunlight transmittance of TiO2@SiO2 nanocomposite films shows a trend of first increasing and then decreasing.4)Using MTES for modification of TiO2@SiO2 nanocomposite films can enhance their hydrophobicity.And the higher the doping ratio of MTES,the better the hydrophobicity of TiO2@SiO2 nanocomposite films.关键词
