摘要
光热转换纳米纤维膜在产业用纺织品等领域中应用广泛。文中利用静电纺丝技术制备聚偏氟乙烯(PVDF)纳米纤维膜,通过在纺丝液中掺杂硫化铋颗粒(Bi_(2)S_(3))和氧化石墨烯颗粒(GO)或纤维膜浸泡盐酸多巴胺的方式对PVDF纳米纤维膜进行改性,得到不同组分纳米纤维膜材料。从形貌、机械性能、热稳定性能、光热转换性能和耐腐蚀性能等方面进行评价,其中PDA-GO-Bi_(2)S_(3)-PVDF纳米纤维膜纤维形貌良好、直径分布均匀、力学性能优良,具有良好的光热转换性能,光热转换温度可达101℃,是未改性PVDF纳米纤维膜的两倍,同时具有良好的热稳定性和耐腐蚀性能。
Photo-thermal conversion nano-fibers are widely used in industrial textiles and other fields.In this paper,the polyvinylidene fluoride(PVDF)nano-fiber membranes were prepared by electro-spinning technology.PVDF nano-fiber membranes were modified by doping bismuth sulfide particles(Bi_(2)S_(3))and graphene oxide particles(GO)in the spinning solution or by impregnating the membrane with hydrochloric acid(HCI)dopamine(DA),and different components of nano-fiber membrane materials were obtained.From morphology,mechanical properties,thermal stability,thermal performance and corrosion resistance to evaluate the membranes,the PDA-GO-Bi_(2)S_(3)-PVDF nano-fiber membrane has good morphology,uniform diameter distribution,excellent mechanical properties and good photo-thermal conversion performance.The photo-thermal conversion temperature can reach 101 ℃,which is twice that of the unmodified PVDF nano-fiber membrane,and has good thermal stability and corrosion resistance.
