摘要
以苯乙烯-马来酸酐共聚物(PSMA)为原料,以N,N-二甲基甲酰胺为溶剂,在不锈钢网上通过静电纺丝法将不同质量浓度的静电纺丝液制备成无纺布状的PSMA膜,再通过喷涂氟碳表面活性剂(FS-51)改变膜对水和油的亲和性得到PSMA/FS-51膜;利用扫描电子显微镜和静态接触角等测试手段表征了所制备膜的微观形貌和表面润湿性。结果表明膜在喷涂氟碳表面活性剂后由超亲油性转变为超亲水性。当静电纺丝液质量浓度为0.45g/mL时,获得的膜的纤维粗细最均匀,PSMA/FS-51膜的油水分离效率达到99%;当静电纺丝液质量浓度为0.50g/mL时,制备的PSMA/FS-51膜的油水分离效率达到100%。此研究提供了一种工艺简单、高效的油水分离方法。
Poly(styrene-co-maleic anhydride)(PSMA) nonwoven films were fabricated by electrospinning method on stainless steel meshes with N,N-dimethylformamide solutions of PSMA as the raw material. We sprayed fluorocarbon surfactant(FS-51) onto the as-prepared nonwoven films to change their water and oil-affinity and obtained the PSMA/FS-51 films. The morphology and surface wettability of the films were characterized by scanning electron microscopy and static contact angle measurement,respectively. These results indicate that the nonwoven films with superoleophilicity exhibit superhydrophilicity through the treatment with fluorocarbon surfactant,presenting the most uniform fiber diameter and 99% of oil-water separation efficiency at the PSMA mass concentration of 0.45 g/mL. Furthermore,the oil-water separation efficiency reaches 100% at the PSMA mass concentration of 0.50 g/mL. This work provides a simple and highly efficient approach for oil-water separation.
