摘　　要： 以含有羧基的氟碳聚合物电纺纤维毡为载体,采用均匀沉淀法于常温溶液中在纤维表面制备分布均匀、直径50nm左右的硫化锌-氟碳聚合物电纺纤维复合光催化材料。在紫外光照220min时,对次甲基蓝降解的残留质量分数为0.03%,低于同等条件下的纳米ZnS粉体,重复5次光降解其仍具有较好的稳定性。 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.
