摘要/Abstract

摘要：

采用Breath Figures法制备了蜂窝状结构的TBT/PMMA前驱体膜, 气相水热处理(VPH)、热裂解前驱体膜, 制备了TiO₂有序孔结构膜, 探讨了气相水热处理、经热裂解去除前驱体膜中聚合物成分过程中结构的变化, 结果表明VPH过程中TBT水解成氢化氧化钛水合物, 形成完善的TiO网络结构, 抵御了高温热裂解去除聚合物过程中“液态化”聚合物的影响, 最终得到有序孔结构的TiO₂膜. 同未经水热处理而直接热裂解得到的TiO2膜相比, 有序孔结构的TiO₂膜紫外光电化学响应显著提高, 其光电流密度约为前者的3倍.

Abstract:

TBT/PMMA organic-inorganic hybrid honeycomb patterned film was prepared by Breath Figures method, then it was suffered vapor phase hydrothermal treatment and transformed into ordered porous TiO₂ film via pyrolysis process. The hole structure was investigated during the vapor phase hydrothermal treatment and pyrolysis process. The results show that, during the vapor phase hydrothermal treatment, TBT hydrolyzes to titanium hydrogen oxide hydrates, forming the strongerTiOnetworks, which therefore prevents the PMMA from “liquefied” in the pyrolysis process, as a result the ordered porous TiO₂film is obtained. Compared with non-hydrothermal treated TiO₂ film, the resulted ordered porous TiO₂ film enhances the photoelectrochemical response and its photocurrent density is increased by 3 times under UV light irradiation.

Key words: Breath Figures, vapor phase hydrothermal treatment, honeycomb pattern, TiO₂ film, ordered porous structure, photoelectrocatalysis
