PAN／插层高岭石复合材料制备及静电纺丝性能
Preparation and Electrostatic Spinning Performance of Polyacrylonitrile/Intercalated Kaolinite Nnanocomposite
摘要
Abstract
Intercalated kaolin was prepared with two dimethyl sulfoxide (DMSO)as precursor,polyac-rylonitrile(PAN)/K-DMSO nanocomposites was prepared by in situ polymerization with PAN and in-tercalated kaolin,and the fiber membranes of PAN/K-DMSO composite were prepared through elec-trostatic 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 ten-sile 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 d 001 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 resist-ance 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 un-treated,cold pressing and heat treatment conditions,respectively,when compared with PAN.关键词
