高性能纤维的表面改性及其与橡胶基体的界面粘合性能研究进展

Research Progress of Surface Modification of High-performance Fiber and Its Interfacial Adhesion Property with Rubber Matrix

从化学改性、物理改性和仿生修饰三个方面介绍高性能纤维的表面改性方法,并阐述提高高性能纤维与橡胶基体的界面粘合性能的研究进展。化学改性是通过化学活化刻蚀和引入活性基团等方式改善高性能纤维与橡胶基体的界面粘合性能,但反应不易控制,且化学改性存在环境污染问题,不易实现工业化;物理改性是通过紫外光辐照接枝以及等离子体、超声波、高能射线等处理对高性能纤维表面进行改性,可有效提高纤维与橡胶基体的界面粘合性能,值得进一步研究;新型环保的绿色浸渍体系及仿生修饰方法将在未来发挥一定的作用。

In this paper,the surface modification methods of high-performance fiber were introduced from three aspects including chemical modification,physical modification and biomimetic modification,and the research progress on the improvement of the interfacial adhesion property between high-performance fiber and rubber matrix was discussed.Chemical modification was realized by chemical etching and introduction of active group,leading to the improvement of the interfacial adhesion.However,the reaction of chemical modification was not easy to control,the process usually brought environmental pollution,and it was difficult for industrialization.Physical modification was mainly to modify the surface of highperformance fiber by UV irradiation grafting and plasma,ultrasonic and high energy ray treatment,which could also enhance the adhesion property,and was worthy of further study.In addition,new environmentally friendly dipping system and biomimetic modification under development would play a role in the future.
