摘　　要：Traditionally,silkworm silk has been used to make high-quality textiles.Nevertheless,various wastes from silk-worm silk textiles that are no longer used are increasing.which is also causing considerable waste and contam-ination.This issue is causing widespread concern in countries that use more silk.Regenerated silk fibroin(RSF)fibers have been shown to be fragile and tender,which prohibits RSF from being widely used as a structural com-ponent.Therefore,enriching the function of silk and enhancing the RSF mechanial properties are important directions to expand the comprehensive utilization of silk products.In the present research,wet spinning was used to create a series of RSF/tungsten disulfide(WS_(2))nanoparticles(NPs)hybrid fiber having distinct WS_(2) nanoparticles concentrations.It was discovered that the temperature of hybrid fibers containing 0.8 wt%RSF/WS_(2) nanoparticles might climb from 20.4℃ to 85.6℃in 1 min and 108.3℃ in 10 min after being exposed to simulated sunlight for a period of one minute and ten minutes.It also had certain antibacterial activity and thermal stability.Fabrics created by hand mixing had outst anding photothermal characteristics under natural sunlight.Further-more,adding WS_(2) nanoparticles might increase the tensile properties of hybrid fibers,which could be caused by the reality that the blending of WS_(2) nanoparticles inhibited the self-assembly of sheets in RSF reaction mixture in a dosage dependent way,as evidenced by the fact that RSF/WSz nanoparticles hybrid fibers had lesser β-sheets material,crystalline nature,and arystalline size.The above performance makes the RSF/WS_(2) nanoparticles hybrid fbers promising candidates for application in photothermal fabrics as well as military dothing.
