摘要

以均苯四甲酸酐(PMDA)、4,4′-二氨基二苯醚(ODA)及纳米TiO₂为原料,采用静电纺丝及热酰亚胺化的方法制备聚酰亚胺/二氧化钛(PI/TiO₂)复合纳米纤维膜,在高温下对PI/TiO₂复合纳米纤维膜进行活化处理,通过正交试验研究了PMDA与ODA摩尔比、纳米TiO₂含量及纺丝液含量对PI/TiO₂活性碳纳米纤维膜吸附性能的影响。结果表明:PMDA与ODA摩尔比为1.03∶1、TiO₂质量分数为3％、纺丝液质量分数为22％时,活性碳纳米纤维薄膜的吸附性能最佳。

Abstract

Polyimide/titanium dioxide (PI/TiO₂) composite nanofiber film was prepared by electrospinning and thermal imidization methods using PMDA,4,4′-diaminodiphenyl ether (ODA) and nano titanium dioxide (TiO₂) as raw materials.The PI/TiO₂ composite nanofiber film was activated at high temperature,and the effects of the molar ratio of PMDA to ODA,the content of nano TiO₂ and the spinning solution formulation on the adsorption performance of the PI/TiO₂ activated carbon nanofiber film were investigated by orthogonal experiment.The results showed that when the molar ratio of PMDA to ODA was 1.03∶1,the mass fraction of TiO₂ was 3% and the mass fraction of spinning solution was 22%,the adsorption performance of the activated carbon nanofiber film was the best.
