自我装配的 nano 阶段基于 silane 的粒子涂层通过大音阶的第五音胶化被准备技术。Tetramethoxysilane 和 3-glycidoxypropyltrimethoxysilane 为自我装配的大音阶的第五音胶化涂层被用作先锋。silane 胶体的粒子尺寸被激光粒子尺寸测量分析。结果显示粒子尺寸在 nano 规模,粒子的直径与增加冲淡时间死亡。胶化浸透层析证明在一个引用大音阶的第五音答案的大分子的相对的分子的团是 1 220-1 240 原子量。一个模拟模型被建议学习 siloxane 结构。答案和电影的红外线的系列证明环氧基树脂债券消失的 Fourier 变换。结果固态原子磁性的回声试验的 13C 和 29Si 显示 Si-O-Si 的形成网络。Potentiodynamic 分析证明自我装配的涂层有优秀腐蚀抵抗。当禁止者显著地改进自我装配的涂层的腐蚀抵抗,盐雾测试证明那 2 甲基哌啶。
Self-assembled nano-phase silane-based particle coating was prepared through sol-gel technique.Tetramethoxysilane and 3-glycidoxypropyltrimethoxysilane were used as precursors for the self-assembled sol-gel coatings.The silane colloidal particle size was analyzed by laser particle size measurement.The results indicate that the particle size is in nano-scale and the diameter of particles deceases with increasing dilution times.Gel permeation chromatography proves that the relative molecular mass of macromolecule in a referenced sol solution is 1220-1240 amu.A simulation model was proposed to study the siloxane structure.Fourier transform infrared spectra of solution and film prove the disappearing of epoxy bond.The results of solid-state 13C and 29Si nuclear magnetic resonance experiments indicate the formation of Si-O-Si network.Potentiodynamic analysis shows that the self-assembled coating has excellent corrosion resistance.Salt fog tests prove that 2-methyl piperidine as inhibitor significantly improves the corrosion resistance of the self-assembled coating.
