摘　　要：为了赋予涤纶(PET)织物良好的阻燃、抑烟性能,实现PET织物的低烟、无卤阻燃,采用浸轧工艺,用水热法制备二硫化钼还原氧化石墨烯(MoS_(2)/RGO)复合材料,并将其用于PET织物的阻燃整理。采用扫描电子显微镜、红外光谱仪以及X射线衍射仪等对MoS_(2)/RGO复合材料以及MoS_(2)/RGO/PET织物的微观形貌与化学结构进行分析;采用垂直燃烧测试仪、烟雾密度箱、接触角仪等对MoS_(2)/RGO/PET织物的阻燃、抑烟性能以及亲水性能进行表征与测试。结果表明:MoS_(2)/RGO复合材料在织物上能够形成良好包覆,且能够有效提高PET织物的热稳定性,在700℃时,其残炭率较纯织物明显提升;MoS_(2)/RGO/PET织物的极限氧指数可提升至28.2%,总热释放量较纯PET织物下降60.5%,烟雾密度降低59.9%,具有良好的自熄性能,损毁长度可降低至10.6 cm。此外,MoS_(2)/RGO复合材料可以赋予PET织物良好的亲水性能,在2.2 s时接触角变为0°,有效改善了PET织物的服用舒适性能。In recent years,the fire risk associated with textile combustion has increasingly drawn people's attention,leading to higher demands for flame-retardant safety in textiles.Polyester terephthalate(PET)possesses properties such as high strength,high temperature resistance,abrasion resistance,corrosion resistance,and light resistance.Therefore,it has been widely used in military,agricultural,industrial,and textile fields.However,PET fabrics are highly flammable and generate toxic gases and dense smoke when burned,causing significant loss to human life and property.This exacerbates the hazards of fires.Consequently,conferring good flame retardancy and smoke suppression properties to PET fabrics holds great practical significance and application value in achieving low-smoke,halogen-free flame retardancy in PET textiles.Graphene is a two-dimensional(2D)honeycomb nano-material composed of sp 2-hybridized carbon atoms.It has garnered considerable attention due to its well-known properties,including superior mechanical strength,extremely high carrier mobility,and excellent thermal conductivity.Graphene has been successfully applied in various fields.Particularly,graphene exhibits high thermal stability.Compared with existing flame retardants,graphene and its derivative,reduced graphene oxide(RGO),are considered environmentally friendly halogen-free flame retardants that can improve the flame retardancy of polymer composites.However,the flame-retardant effect of a single agent is limited,especially in suppressing the dense smoke generated during the combustion of PET.The inhibitory effect of graphene-based flame retardants is not ideal.To address this,we introduce molybdenum disulfide nano-materials.Molybdenum disulfide nano-materials prepared by hydrothermal method exhibit excellent thermal stability and can maintain the stability of the layered structure at higher temperatures,thus exerting the barrier effect of the layered structure.The transition metal molybdenum promotes the formation of a char layer during fabric com
