摘要
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。
The polysulfonamide has some good properties such as heat resistance, thermal stability and flame re- tardance. However, the conventional polysulfonamide has a relative high volume resistivity and poor ultraviolet resistance etc. It leads to some difficulties in the following manufacturing procedures and limits its application in the field of protective clothing. Through a prelimary reference summary and analysis on the development of functional polysulfonamide, the mechanical properties and electrocon- ductive property of CNT, the ultraviolet absorbing capacity and shielding performance of nano-TiO2 particle are introduced briefly. The mechanism of polymer-particle blending system and surface modifi- cation are also investigated. All these are the research foundation for the development of the functional polysulfonamide nano-composites.
