摘　　要：Developing an advanced individual protection cloth is a pivotal factor in combating global pathogen epidemics.However,formidable challenges are posed by the triangularity imbalance effect,necessitating the simultaneous fulfillment of require-ments for high comfort,high safety,and mass production.In this study,a mass-producible hybrid polytetrafluoroethylene nanofiber mat(HPNFM)was developed by integrating technologies of organic-inorganic hybridization and membrane asynchronous stretching.Exceptional comfort was attained by conferring waterproofing and breathability attributes,achieved through the radial island-chain architecture exhibiting hydrophobicity and nanoporosity.Furthermore,through the incorpo-ration of high-efficiency anti-pathogen nanoparticles,the HPNFM ensures high safety,demonstrating active antibacterial and antiviral effects.This is achieved through the synergistic effects of electrostatic induction and reactive oxygen species-based pathogen inactivation.More significantly,an HPNFM-based individual protective suit is designed and manufactured,which successfully encapsulates the advantages of high comfort,safety,and mass production,displaying competitiveness as a commercial product.Positioned as a viable strategy,this work holds substantial potential for practical applications in responding to future epidemics.
