摘要
以聚丙烯腈和磷烯为原料,利用静电纺丝制备了5%~20%不同磷烯含量的聚丙烯腈/磷烯复合纤维膜。采用扫描电子显微镜、X射线衍射、热线法、激光法、垂直燃烧对磷烯和复合纤维膜进行结构形貌、导热性能和阻燃性能表征。结果表明,磷烯的引入提高了聚丙烯腈纤维的阻燃性能,当磷烯含量超过5%时复合纤维膜可达阻燃标准UL-94 V-0级;复合纤维膜的导热系数随着磷烯含量增加先升高再降低,当磷烯含量为10%时复合纤维膜的热导率为0.156 W/(m·K),是纯聚丙烯腈纤维0.048 W/(m·K)的3倍以上。该工作拓宽了聚丙烯腈纤维在可穿戴纺织品中的应用。
Polyacrylonitrile/phosphorene composite fiber membranes with 5%~20%different phosphorene content were prepared by electrospinning using polyacrylonitrile and phosphorene as raw materials.The structure,thermal conductivity and flame-retardant properties of phosphorene and composite fiber membranes were characterized by scanning electron microscopy,X-ray diffraction,hot wire method,laser method and vertical combustion.The results show that the introduction of phosphorene improved the flame retardancy of polyacrylonitrile fiber.When the content of phosphorene exceeded 5%,the composite fiber membrane can reach the flame-retardant standard UL-94 V-0.The thermal conductivity of the composite fiber membrane increased first and then decreased with the increase of the content of phosphorene.When the content of phosphorene was 10%,the thermal conductivity of the composite fiber membrane was 0.156 W/(m·K),which was more than 3 times that of pure polyacrylonitrile fiber[0.048 W/(m·K)].This work broadened the application of polyacrylonitrile fiber in wearable textiles.
