摘要:
通过溶液浸渍法,用硅烷偶联剂γ-(2,3-环氧丙氧)丙基三甲氧基硅烷对纳米级SiO2溶胶表面改性,再利用其作为媒介与聚四氟乙烯(PTFE)粒子均匀结合在三聚氰胺海绵(MS)骨架上,热处理后构造微观粗糙疏水结构。用红外光谱、扫描电子显微镜、水接触角对海绵进行了表征。结果表明:SiO2/PTFE粗糙结构能提高MS的疏水吸油效果,平均静态疏水角达到141°,对柴油、甲苯、四氯化碳等多种油都有较好的吸收效果,其中对四氯化碳的吸收量最高为136 g/g。用改性SiO2/PTFE-MS吸取水面浮油和水下油滴,油相被改性SiO2/PTFE-MS快速吸收,容器中水量不变。
Abstract:
The surface of nano-SiO2 sol was modified with γ-(2,3-epoxypropoxy)propytrimethoxysilane by the impregnation method,and then the modified SiO2 sol was used as the medium to combine with the polytetrafluoroethylene(PTFE) particles uniformly on the melamine sponge(MS) skeleton. After heat treatment,the microstructure was constructed as a coarse and hydrophobic structure. Modified sponges were characterized by ?infrared?spectroscopy, scanning electron microscopy and water contact angle measurements. The results showed that the rough structure of silica/polytetrafluoroethylene improves the hydrophobic and oil-absorbing effect of melamine sponge,the average static hydrophobic angle reaches 141°,and it has good adsorption effect on diesel oil,toluene,carbon tetrachloride and other oils,among which the adsorption amount of carbon tetrachloride is up to 136 g/g. Water floating oil and underwater oil droplets are absorbed by modified SiO2/PTFE-MS. The oil phase is quickly absorbed by modified SiO2/PTFE-MS,and the amount of water in the container remains unchanged.
