摘要
采用静电纺丝法制备了聚丙烯腈(PAN)/聚醋酸乙烯酯(PVAc)复合纳米纤维膜。利用原子力显微镜(AFM)、电子显微镜(SEM)分析了纤维的直径分布、整体形貌及单根纳米纤维的表面形貌;利用傅里叶变换红外光谱(FT-IR)分析了PAN、PAN/PVAc、PVAc纳米纤维膜的化学组成;同时借助热重(TG)分析了PVAc的加入对复合纤维膜热性能的影响。结果表明,当m(PAN)∶m(PVAc)=5∶5、质量分数为10%时,所得纤维膜最有利于制备聚合物电解质膜;PAN与PVAc之间产生配位键,从而提高了纤维膜的热性能。
PAN/PVAc composite nanofibers membrane was fabricated via electrospinning. AFM and SEM were used to investigate the distribution and overall morphology of nanofiber membrane as well as the surface morphology of single specific nanofiber. FT-IR and TG were employed to study the molecular structure and the heat re sistance properties, respectively. The results show that when the weight ratio of PAN/PVAc is 5 -： 5 and the mass fraction is 10%, the membrane fabricated is most favorable for polymer electrolytes. The heat resistance of nanofibers membrane is improved because of the presence of new chemical bond.
