摘要

将PAN纺丝液通过静电纺喷丝成网,制备成静电纺PAN纳米纤维膜,并用盐酸羟胺对其进行化学改性;通过铁离子与改性PAN中的偕胺肟基团进行配住反应,得到具有光催化功能的静电纺PAN铁配合物。首先观察了不同质量分数纺丝液纤维的表面形态、改性前后及铁配合反应后纤维的表面形态。其次对PAN纳米纤维、改性PAN纳米纤维、配合不同铁浓度的PAN纳米纤维、改性前后掺杂TiO_2的静电纺PAN纳米纤维进行了红外光谱分析和紫外可见光谱分析。最后研究了其光催化染料降解的效果。实验结果表明,静电纺PAN比较理想的纺丝液质量分数为20%;静电纺PAN铁配合物光催化性能优异,催化效果较普通PAN铁配合物有明显提升,且不同铁浓度的纳米纤维膜光催化效果随上铁量的增加而增强。
The PAN spinning solution was jetted into net shape by electrospinning method,to prepare PAN nanofiber membrane,which was then treated by chemical modification through hydroxylamine hydrochloride.Through the coordination reaction between iron and amidoxime group in modified PAN,the electrospun PAN iron complexes with photocatalytic function was prepared.Firstly,the surface morphology of the fibers with different mass fraction of spinning solution,the surface morphology of the fiber before and after modification,and the surface morphology of the fiber after complex reaction were observed.Secondly,the PAN nanofibers,modified PAN nanofibers,PAN nanofibers with different iron concentration,electrospun PAN nanofibers before and after TiO_2 doping were analyzed using infrared spectra and ultraviolet-visible spectra.Finally the samples photocatalytic performances for dye degradation were studied.The experimental results show that the ideal spinning solution mass fraction for fabricating PAN is20%.The photocatalytic performance of PAN-iron complex is excellent,and the catalytic efficiency is significantly increased compared with that of common PAN-iron complex.The photocatalytic efficiency of nanofiber membrane increases with the increase of iron content.
