Abstract:

The fluoropolymer with carboxyl group nano-fiber electrospun mats as the carrier and template, the complex formation between carboxyl on fluoropolymer electrospun fiber surface with zinc ion, and then the zinc sulfide (ZnS) nanoparticles of about a few to several decade nanometers in size were immobilized on the surface of fluoropolymer electrospun fiber through solution precipitation. The degradation of methylene blue solution is performed by ZnS-fluoropolymer nanocomposites under UV irradiation and results show that the ZnS-fluoropolymer nanocomposites have good photocatalytic ability, reusing and stability.

Key words: zinc sulfide,fluoropolymer,electrospun fiber,photocatalytic activity
