摘　　要：通过层层自组装法,使用低表面能物质三氨基三甲氧基硅烷(APS)对具有微纳米复合阶层结构的玉米芯进行修饰,制备出超疏水-超亲油玉米芯滤料。利用扫描电子显微镜(SEM)分析其微观形貌,并进行了油水分离性能测试及耐酸碱、耐高温、抗菌性测试。结果表明:改性后的玉米芯在极端环境下仍然具有良好的油水分离性能,对水的静态接触角为156°;回收后的油污还可重复利用,其使用方便,成本低廉。可为油水分离以及超疏水-超亲油材料的制备提供新思路。Through layer by layer self-assembly method,superhydrophobic and superoleophilic corn cob filter material was prepared by using triamino-trimethoxysilane(APS),a low surface energy material,to modify the micro-nano composite layer structure of corn cob.Scanning electron microscope(SEM)is used to analyze the micromorphology,oil-water separation performance,acid and alkali resistance,high temperature resistance and antibacterial resistance are analyzed.The results show that the modified corn cob still has good oil-water separation performance under extreme environment,and the static contact angle to water is 156°.The recycled oil can also be reused,which is convenient to use and low cost.It can provide new ideas for oil-water separation and the preparation of superhydrophobic and superoleophilic materials.
