Abstract:

Hollow TiO2 microspheres were fabricated with PS as template, tetrabutyl titanate as titanium resource and ammonium as catalyst. Then, hollow TiO2 microspheres were introduced into polyacrylate emulsion by physical blending method. The effect of hollow size and dosage of hollow TiO2 microspheres on light reflection, thermal conductivity and mechanical property of composite film were investigated. The results show that hollow TiO2 microspheres can significantly improve the properties of polyacrylate film. The hollow size and dosage of hollow TiO2 microspheres have different degree influence on properties of composite film. The properties of composite film firstly increase and then decrease with increasing of hollow size and dosage of hollow TiO2 microspheres. When the hollow diameter and the dosage of hollow TiO2 microspheres is 300 nm and 1%, respectively, the thermal insulation properties and mechanical properties of the composite membrane are optimal.

Key words: Hollow TiO2 spheres, polyacrylate, composite film, thermal insulation, mechanical property
