摘要
通过凝胶-溶胶法制备纳米二氧化硅粒子,并使用二甲基二乙氧基硅烷进行疏水改性。采用直接浸泡法在100目不锈钢网表面成功构造出了纳米级粗糙结构。并研究了浸泡次数和老化时间对样品表面润湿性的影响,同时用自制的油水分离装置进行油水分离实验。结果表明:样品对水的接触角达155°,油水分离效率达92%。
In this study,nano-silica particles were prepared by gel-sol method,and hydrophobic modification was carried out using dimethyl diethoxysilane.We construct the nanoscale rough structure on the surface of 100 mesh stainless steel mesh by direct immersion method.In addition,the effects of soaking times and aging time on the surface wettability of the samples were studied,and the oil and water separation experiments were carried out with self-made oil and water separation devices.The results showed that the samples of water contact Angle of 155°,oil-water separation efficiency up to 92%.
