聚砜酰胺具有良好的耐热性、热稳定性和阻燃性能,但常规聚砜酰胺纤维存在体积比电阻高和抗紫外线性能差等缺陷,导致后续加工困难,限制了其在防护类服装领域的应用。通过对功能性聚砜酰胺纤维制备及改良现状的概括与分析,重点介绍了碳纳米管基本力学和导电性能以及纳米二氧化钛紫外线吸收和屏蔽功能,阐述了碳纳米管和纳米二氧化钛对聚砜酰胺纤维的共混和改性机理,为功能性聚砜酰胺纳米复合材料的开发奠定基础。
Polysulfone amide has good heat resistance, thermal stability and flame retardancy, but conventional polysulfonamide fiber has the defects of high volume resistivity and poor UV resistance, which makes subsequent processing difficult and limits its application in the field of protective clothing Applications. Through summarizing and analyzing the preparation and improvement status of functional polysulfonamide fiber, the basic mechanical and electrical properties of carbon nanotubes as well as the ultraviolet absorption and shielding function of nano-sized titanium dioxide are introduced. The effects of carbon nanotubes and nano-titanium dioxide on polysulfonamide fiber Blend and modification mechanism, which laid the foundation for the development of functional polysulfone amide nanocomposites.
