We investigated the properties of synthetically produced organic-inorganic hybrid coatings by a sol-gel process. The properties of organic-inorganic hybrid materials arise from the synergism between the properties of the individual components. One of the typical way to synthesize the organic-inorganic hybrid materials is to use silica and silanes. A colloidal silica sol was used as an inorganic material. Methyltrimethoxysilane and phenyltrimethoxysilane were used as the trifunctional organoalkoxysilanes. Hybrid sols of colloidal silica and silanes were synthesized as a function of reaction time and methyltrimethoxysilane/phenyltrimethoxysilane ratio by a sol-gel process. Physical properties of sol solutions such as stability, viscosity, and transmittance were investigated. The surface roughness and surface free energy of the coatings were also measured.
我们通过溶胶-凝胶法研究了合成制备的有机-无机杂化涂层的性能。有机-无机杂化材料的性能源于各组分性能之间的协同作用。合成有机-无机杂化材料的一种典型方法是使用二氧化硅和硅烷。胶体二氧化硅溶胶用作无机材料。甲基三甲氧基硅烷和苯基三甲氧基硅烷用作三官能有机烷氧基硅烷。通过溶胶-凝胶法，根据反应时间和甲基三甲氧基硅烷/苯基三甲氧基硅烷比例合成了胶体二氧化硅和硅烷的杂化溶胶。研究了溶胶溶液的物理性质，如稳定性、粘度和透光率。还测量了涂层的表面粗糙度和表面自由能。
