| 中文摘要: |
| 本研究采用高压均质和静电纺丝技术,分别制得纤维素纳米纤维(CNF)和聚丙烯腈(PAN)纳米纤维膜,利用真空负载法构筑PAN/CNF复合膜,并探究CNF负载量对其理化性质的影响,以及PAN/CNF复合膜的油水分离性能。结果表明,CNF在PAN纳米纤维膜表面成功负载,PAN/CNF复合膜呈明显的双层结构。未负载CNF的PAN纳米纤维膜(PAN/CNF-0)平均孔径为0.234 μm,当CNF实际负载量为1.16 g/m2时,制得PAN/CNF-2的平均孔径降至0.182 μm,且CNF层存在纳米级孔结构。随着CNF负载量的增加,PAN/CNF复合膜的透气度、水接触角与水浸润时间均持续降低。此外,PAN/CNF-2的水下油接触角为155°,水通量可达3 569 L/(h·m2),相较于PAN/CNF-0(143°和4 412 L/(h·m2)),其亲水疏油性能明显提升。 |
| Abstract: |
| In this study, cellulose nanofiber (CNF) and polyacrylonitrile (PAN) nanofiber film were prepared, respectively, via high-pressure homogenization and electrospinning techniques. The PAN/CNF composite films were constructed using the vacuum loading method, and the effects of CNF loading capacity on the physicochemical properties and oil-water separation performance of PAN/CNF composite films were investigated. The results indicated that CNF successfully loaded to the surface of PAN nanofiber film, with PAN/CNF composite films exhibiting a double-layer structure. The average pore size of the PAN nanofiber film without CNF loading (PAN/CNF-0) was 0.234 µm. When the actual CNF loading capacity reached 1.16 g/m², the average pore size of the prepared PAN/CNF-2 decreased to 0.182 µm, and the CNF layer exhibited a nanoscale porous structure. As the CNF loading increased, the air permeability, water contact angle, and water wetting time of PAN/CNF composite films all decreased continuously. Furthermore, PAN/CNF-2 exhibited an underwater oil contact angle of 155° and a water flux of 3 569 L/(h·m²), demonstrating significantly enhanced hydrophilic and oleophobic properties compared to PAN/CNF-0 (143° and 4 412 L/(h·m²)). |
