With fluoropolymer containing carboxyl group electrospun fiber mats as the carrier,zinc sulfide(ZnS) particles of diameter of about 50 nm were uniformly immobilized on the surface of fluoropolymer electrospun fiber through solution precipitation at room temperature.The degradation of methylene blue in solution was performed by ZnS-fluoropolymer composites under UV irradiation.The results show residual mass fraction of methylene blue is 0.03% by ZnS-fluoropolymer composites at 220 min,and is lower than that of ZnS nanoparticles under the same condition.The ZnS-fluoropolymer composites have good photocatalytic activity and stability after 5 repeated tests.
