摘要

受石质古迹表面天然保护膜的启发,通过仿生技术,以十六烷基三甲基溴化铵(CTAB)为有机模板调控正硅酸乙酯(TEOS)的水解缩合,在青石表面制备出二氧化硅防护膜.制备出的防护膜具有优良的耐酸、耐污性能,憎水性有所增加,但仍维持其亲水的性能.用红外光谱仪对仿生膜的结构进行表征,表明其主要成分为二氧化硅.

Abstract

Enlightened by the natural protective films on the surfaces of historic stones,the silicon dioxide protective films were prepared by hydrolysis of TEOS regulated by organic template of CTAB in the way of biomimetic synthesis.The prepared bioinspired films had the excellent resistance to acid and soil,and was water-repellent,but still maintained the good hydrophilicity.The structure of bioinspired films having been analyzed by FTIR showed that the films were mainly composed SiO2.
