在水溶液中,氧化石墨烯(GO)/阳离子聚丙烯酰胺(CPAM)复合膜通过一个独特的自组装过程制备,随后在室温下,硼氢化钠溶液快速还原中,产生基质负载的导电性纤维膜。利用电解原理在导电性纤维膜表面上镀上一薄层Cu微纳米颗粒。在光滑的纤维骨架表面通过复合Cu微纳米颗粒构筑具有一定粗糙度的微纳米结构,同时在Cu微纳米颗粒表面修饰上低表面能的硬脂酸,制备具有超疏水-超亲油界面特性的复合材料,接触角到达153°,以实现高效油水分离的目的。
In aqueous solution, GO / CPAM composite membranes were prepared by a unique self-assembly process followed by rapid reduction of the sodium borohydride solution at room temperature to produce matrix supported conductive fiber membranes . The principle of electrolysis is used to coat a thin layer of Cu micro-nano particles on the surface of the conductive fiber membrane. On the surface of a smooth fiber skeleton, a micro-nano structure with a certain degree of roughness was formed by compound Cu micro-nano-particles, and stearic acid with a low surface energy was modified on the surface of the micro-nano-Cu particles to prepare a super hydrophobic-super oleophilic interface Composites with a contact angle up to 153 ° for the purpose of efficient oil-water separation.
