聚丙烯腈/纤维素纳米纤维复合膜的制备及其油水分离性能研究
Study on Fabrication of PAN/CNF Composite Films and Its Oil-water Separation Properties
摘要
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 ef-fects of CNF loading capacity on the physicochemical properties and oil-water separation performance of PAN/CNF composite films were inves-tigated.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)).关键词
