采用傅里叶变换红外光谱、电子能谱分析和接触角测量等方法研究了3-甲基丙烯酰氧丙基三甲氧基硅烷（MSL）、3-环氧丙氧丙基三甲氧基硅烷（ESL）和乙烯基三甲氧基硅烷（VSL）在聚甲基丙烯酸甲酯上的辉光放电聚合反应。单体流速影响聚合物沉积速率和聚合物元素组成。红外光谱表明，从不同的硅烷制备的聚合物之间的化学结构的差异。所得的所有聚合物含有类似的化学基团，例如CH 3、CH 2、SiOSi和SiOC。从MSL和ESL沉积的聚合物在最上层含有高度亲水性官能团，如COH、SiOH和CO，而从VSL沉积的聚合物含有高度疏水性官能团，如CH 3基团。通过ESCA和接触角测量的化学分析给出了由MSL和ESL制备的聚合物的相似性的证据，与由VSL制备的聚合物的差异形成对比。
Glow discharge polymerization among such reactive functional silances as 3-methacryloxypropyltrimethoxysilane (MSL), 3-glycidoxypropyltrimethoxysilane (ESL), and vinyltrimethoxysilane (VSL) on poly(methyl methacrylate) was investigated by means of Fourier transform infrared spectroscopy, ESCA analysis, and contact angle measurement. Flow rate of monomer influenced both polymer deposition rate and polymer elemental composition. Infrared spectra showed differences in chemical structure among the polymers prepared from the different silanes. All of the polymers obtained contained similar chemical groups such as CH3, CH2, SiOSi, and SiOC. Polymers deposited from MSL and ESL contained highly hydrophilic functional groups like COH, SiOH, and CO on the uppermost layer while that from VSL contained highly hydrophobic functional groups like CH3 groups. Chemical analysis by ESCA and contact angle measurement gave evidence for the similarity of the polymers prepared from MSL and ESL, in contrast with the differences of the polymers prepared from VSL.
