摘要 以二甲基亚砜为前驱体制备插层高岭石(K-DMSO),通过原位聚合制备聚丙烯腈(PAN)与K-DMSO 的复合物,利用静电纺丝技术制备PAN/K-DMSO复合纤维膜。采用XRD,FTIR,TEM和TGA研究PAN/K-DMSO复合物的微观形态和热性能,并采用SEM,POM和拉伸试验机对其纤维膜的形貌和拉伸强度进行测试表征。结果表明:PAN/K-DMSO中含有高岭石的内外羟基峰,表征层间距的d001值随PAN进入高岭石的层间而增大,部分高岭石被剥离形成厚度为2~5nm的片层结构分散在PAN基体中。K-DMSO的加入使PAN的耐热性提高,PAN纤维膜的直径减小,拉伸强度增加。PAN与K-DMSO的质量比为8:1时,PAN/K-DMSO纤维膜的拉伸强度与PAN相比,在未处理,冷压和热处理的情况下分别提高了0.92,1.73MPa和1.96MPa。

Abstract:Intercalated kaolin was prepared with two dimethyl sulfoxide (DMSO) as precursor, polyacrylonitrile(PAN)/K-DMSO nanocomposites was prepared by in situ polymerization with PAN and intercalated kaolin, and the fiber membranes of PAN/K-DMSO composite were prepared through electrostatic spinning technology. The microstructure and thermal properties of intercalation composites PAN/K-DMSO were studied by using XRD, FTIR, TEM and TGA. The micro-morphology and tensile strength of fiber membranes were characterized by SEM, POM and tensile testing machine. The results show that PAN/K-DMSO containing hydroxyl group peak which belong to the kaolin. The d001 layer spacing value of kaolinite increases with PAN into interlayer, and part of kaolinite is peeled and forms lamellar structure with thickness of 2~5nm dispersed in a polymer matrix. The heat resistance of PAN/K-DMSO composite is increased with the addition of K-DMSO. The diameter of PAN fiber membranes decreases and the tensile strength increases with the increase of K-DMSO.When the mass ratio of the PAN and K-DMSO is 8:1,the tensile strength is increased by 0.92,1.73MPa and 1.96MPa in untreated, cold pressing and heat treatment conditions, respectively,when compared with PAN.
