硅溶胶改性有机-无机杂化纳米薄膜的制备及性能测试
Preparation and Characterization of Organic-Inorganic Hybrid Nanofilms with Colloidal Silica
摘 要
采用溶胶-凝胶法,以甲基三乙氧基硅烷(MTEOS)和正硅酸乙酯 (TEOS)为原料,制备有机-无机杂化薄膜,又采用纳米硅溶胶对有机-无机杂化薄膜进行改性.硅溶胶改性后有机-无机杂化纳米薄膜透明而且光滑,大大提高了薄膜的临界厚度.以热失重(DTA/TG)、傅立叶红外光谱(FTIR)手段研究了薄膜材料的结构及性能随温度的变化,并对涂覆于不锈钢表面上的硅溶胶改性后有机-无机杂化薄膜的防腐蚀性能进行了实验检测.结果表明,硅溶胶改性后有机-无机杂化薄膜的热稳定性能明显提高,并具有优良的抗腐蚀性能.

Abstract
Organic-inorganic hybrid films were prepared by sol-gel process,using methyltriethoxysilane(MTEOS) and tetraethoxysilane(TEOS) as precursors.With the addition of colloidal silica nanoparticles,the preparation and characterization of the hybrid films were improved.The prepared hybrid nanofilms were dense,uniform and defect-free.The critical thickness of the hybrid nanofilms was increased with the addition of the colloidal silica.The relationship between structure and temperature was investigated by DTA/TG and FTIR.The corrosion resistance performance of the hybrid nanofilms applied on stainless steel was tested.The nanofilms showed high heat stability and excellent corrosion resistant properties.So the new nanofilms can provide long-term and environmentally corrosion protection.
