聚丙烯酸／蒙脱土／TiO2复合材料的紫外光降解

The polyacrylic acid-montmorillonite-TiO2 composite was successfully prepared by adding TiO2 into polyacrylic acid-montmorillonite composite and by using high temperature quick reaction. Through wet process and dry process under irradiation of ultraviolet, the degradation of the composite was performed, the degradation process investigated, and characterized before and after degradation through infrared and SEM. The result indicated that compared to dry degradation, wet degradation had much better degradation rate and degree of degradation. Moreover, the UV-degradation ability of polymer could obviously be improved by adding TiO2 into the composite, indicating that the polyacrylic acid-montmorillonite-TiO2 composite was a new environment-friendly material.
