A sol-gel has been prepared by using allyltrimethoxysilane (ATMS) as precursor, ethanol as homogenizer as well as solvent, and hydrochloric acid as catalyst. The sol-gel was employed for the coating treatment of aluminum. Self-assembled monolayer (SAM) with allyltrichlorosilane (ATCS) is another method used for the metal surface treatment in the present work. The treated metal surfaces were characterized with reflection adsorption infrared spectra (RAIR). Detailed interpretation and vibrational assignment have been given to the collected IR spectra of the sol-gel, xerogel and surface films of ATMS and the SAM of ATCS on aluminum as well as pure silanes. A series of investigation of the UV exposure and temperature effects has been carried out. Results from the investigation indicate that the UV radiation exposure or the high temperature thermal treatment will induce a chemical process on the organosilica coated surfaces.
以烯丙基三甲氧基硅烷（ATMS）为前驱体，乙醇为均化剂及溶剂，盐酸为催化剂制备了溶胶-凝胶。该溶胶-凝胶用于铝的涂层处理。用烯丙基三氯硅烷（ATCS）进行自组装单分子层（SAM）是本工作中用于金属表面处理的另一种方法。用反射吸附红外光谱（RAIR）对处理过的金属表面进行了表征。对溶胶-凝胶、干凝胶以及ATMS的表面膜和铝上ATCS的SAM以及纯硅烷的收集红外光谱进行了详细的解释和振动归属。进行了一系列关于紫外线照射和温度影响的研究。研究结果表明，紫外线辐射暴露或高温热处理会在有机硅涂层表面引发化学过程。
