碳纳米纤维在制备导电复合高分子材料中的应用

Application of Carbon Nanofi bers in Preparation of Conductive Composite Polymer Materials

利用功能化高分子复合材料、碳纳米纤维与常规聚合物复合制备高性能化学高分子材料在学术界和工业界引发各种兴趣,但是关于利用通用高分子制备导线高分子材料和CNF依旧面临一些问题,主要包括表面修饰和分散程度的关系、CNF表面修饰以及CNF逾渗值过高等等,现如今,研究热点着重于研究功能化CNF的结构、导电性能以及分散形态之间的关系,构建有关的导电物理模型,研讨有关导电机理。

The use of functionalized polymer composites,carbon nanofibers and conventional polymers to prepare high-performance chemical polymer materials has aroused various interests in academia and industry.However,CNF still faces some problems regarding the use of general polymers to prepare conductor polymer materials,including the relationship between surface modification and dispersion degree,the surface modification of CNF and the high percolation value of CNF,etc.Nowadays,research focuses on the relationship between the structure,conductivity and dispersion form of functionalized CNF,and the construction of relevant conductive physical models,as well as the discussion of relevant conductive mechanisms.
