摘要
聚酰亚胺作为一种新型聚合物半导体光催化剂,具有良好的稳定性及出色的光响应能力,在光催化领域中展现出极大的发展潜力,但也存在比表面积小和电子-空穴复合严重等问题,而对聚酰亚胺进行形貌调控、元素掺杂和半导体复合等改性可以提高它的光催化性能。综述了聚酰亚胺的合成、改性方式及酐类胺类单体对聚酰亚胺性能的影响,并对未来聚酰亚胺在光催化领域的发展进行了展望。
As a new type of polymer semiconductor photocatalyst,the polyimide has good stability and excellent light response-ability,showing great development potential in the photocatalysis field,while it also has disadvantage of small specific surface area and may cause serious electronhole recombination.Photocatalytic performance of polyimide can be enhanced by methods,such as adjusting its morphology,doping elements and combining it with other semiconductors.The synthesis and modification methods of polyimide and effect of anhydride amine monomers on its properties of polyimide are reviewed.The development perspectives of polyimide in the field of photocatalysis has also been proposed.
