介绍了酚醛树脂(PF)的性质及对其增强改性的必要性，阐述了对碳纳米管(CNTs)进行修饰预处理的原因，并对几种修饰预处理方法进行了归纳对比；然后综述了 CNTs/PF基复合材料的制备方法和性能，归纳分析了三种制备方法———溶液共混、干粉混合和原位聚合的优缺点，以及复合材料的力学性能、热学性能和摩擦学性能；最后指出，不能完全有效地阻止 CNTs 在 PF 基体中的团聚以及CNTs的增强机理不成熟是现阶段研究 CNTs/PF 基复合材料面临的两个问题，并针对存在的问题给出了CNTs/PF基复合材料今后的主要研究方向。
The properties and reinforcement necessity of phenolic resin (PF)are introduced.The causes of modifing carbon nanotubes(CNTs)are expunded and several modification methods are compared.Three kinds of methods of preparing CNTs/PF matrix composite are summarized,including solution blending,dry powder mixing and in-situ polymerization.Meanwhile,their advantages and weakness are analyzed comparatively,and then the mechanical,thermal and tribological properties of the composites are reviewed.Finally,two problems are pointed out in the present research of CNTs/PF matrix composite.One is that carbon nanotubes′reunion in the PF substrate can′t be prevented effectively and thoroughly,and the other is the vagueness of carbon nanotubes′reinforcement mechanism.For the above problems,main research directions in the future are proposed.
