模板法制备电纺聚吡咙纳米纤维

Polypyrrolone is a class of heat-resistant, radiation-resistant and chemical-resistant high performance ladder or semi-ladder polymers. The project intends to explore the large-scale preparation of electrospun polypyrrolone nanofibers by using polymer templates: 1) formulating the electrospinning solution by using some cheap thermally decomposable polymer as the template, using the compound with four carboxylic acid groups and the tetraamine compound as the monomers for the formation of “amino/carboxylic quasi-polymer; 2) electrospinning the solution to form the electrospun composite nanofibers of the template polymer and the "amino/ carboxylic quasi-polymer"; 3) heating the composite nanofibers for converting the “amino/carboxylic quasi-polymer” into polypyrrolone structure and for decomposing the template polymer, finally forming the electrospun polypyrrolone nanofibers. The process parameters would be optimized for achieving the goal of preparing high-performance electrospun polypyrrolone nanofibers in large-scale. The success of this project would be a significant contribution to our great haze treatment project.
