摘　　要：通过水热法制备了二硫化钼(MoS_(2))纳米微球,再采用浸渍法将不同浓度的MoS_(2)负载到经聚多巴胺(PDA)改性后的聚丙烯(PP)熔喷非织造材料表面,制备MoS_(2)@PP复合熔喷非织造材料。结果显示:合成的MoS_(2)花状微球粒径为1μm左右,比表面积为22.77 m^(2)/g。将MoS_(2)负载到PP熔喷材料表面,当MoS_(2)的负载质量浓度为0.75 mg/mL时,MoS_(2)-0.75@PP复合熔喷材料对水体中罗丹明B(RhB)的吸附效率最高,约为99.00%,经5次循环吸附后,其对RhB的吸附效率仍有70.00%。MoS_(2)-0.75@PP复合熔喷材料对RhB的吸附过程是自发的,以化学吸附为主。与原PP熔喷材料相比,MoS_(2)-0.75@PP复合熔喷材料的力学性能仅有略微下降。Molybdenum disulfide(MoS_(2))nanospheres are prepared by the hydrothermal method,and MoS_(2)with different concentrations are loaded onto the surface of polypropylene(PP)melt-blown nonwoven material modified with polydopamine(PDA)by impregnation method to prepare MoS_(2)@PP composite melt-blown materials.The results show that the MoS_(2)flower-shaped microspheres have a particle size of around 1μm,and specific surface area of 22.77 m^(2)/g.With 0.75 mg/mL of MoS_(2),the adsorption efficiency of MoS_(2)-0.75@PP com⁃posite melt-blown material for Rhodamine B(RhB)solution is about 99.00%.After 5 cycles,its adsorption effi⁃ciency for RhB still reaches 70.00%.The adsorption process of MoS_(2)-0.75@PP composite melt-blown materi⁃als for RhB is spontaneous,mainly dominated by chemical adsorption.The mechanical properties of MoS_(2)-0.75@PP composite melt-blown materials have only slightly decreased compared with the original PP meltblown material.
