使用的SiO2-类层之间的反应性等离子体聚合物膜和金基板的粘附促进层进行比较，以自组装的单层的十二烷硫醇和裸金。通过改变原料气比例和工艺输入功率来优化氧化硅膜的化学结构。5s氧等离子体改性的SiO2类薄膜沉积。已经发现，从六甲基二硅氧烷中分离的聚硅氧烷对于制备用于随后沉积的反应性聚合物层的共价键合的表面是至关重要的。薄膜的化学结构和反应性进行了研究，使用红外反射吸收光谱，XPS，接触角测角仪和SPR光谱。
The use of SiO2-like layers as adhesion-promoting inter-layers between a reactive plasma polymer film and a gold substrate is compared to a self-assembled monolayer of dodecanethiol and to bare gold. The chemical structure of the silicon oxide film is optimized by varying feed gas ratios and process input power. A 5 s oxygen plasma modification of the SiO2-like film deposited. from hexamethyldisiloxane has been found to be vital to prepare the surface for covalent bonding of the subsequently deposited reactive polymer layer. Film chemical structures and reactivity have been studied using IR reflection-absorption spectroscopy, XPS, contact angle goniometry and SPR spectroscopy.
