摘要
采用电化学合成法,分别以对氨基苯甲酸/双酚A(PABA/BPA)、对氨基苯甲酸/聚乙二醇600(PABA/PEG600)为反应体系,修饰高模碳纤维(HMCF)表面;研究了这两种体系下的连续电化学合成工艺,以及反应电位对HMCF性能的影响。通过SEM照片可见,HMCF经PABA/BPA体系修饰后表面存在化合物涂层;由红外光谱分析证实,表面化合物的红外谱图中存在明显的酯基峰。层间剪切强度(ILSS)结果表明,经PABA/BPA体系修饰过的HMCF复合材料的ILSS可达到73.1 MPa,表明PABA/BPA体系对HMCF具有较好的修饰效果。
Electrochemical synthesis was used to decorate the surface of high-module carbon fiber with PABA/ BPA and PABA/PEG600 as synthesis systems. Continual electrochemical synthesis process in this two synthesis systems was developed and the effect of the synthesis potential on carbon fiber performance were studied . There was compound coat on surface of carbon fiber decorated by PABA/BPA synthesis system shown from SEM image. From FTIR analysis, ester group peak exists in compound coat. As a result, interlaminar shear strength of HMCF/composite decorated by PABA/BPA synthesis system can reach 73.1 MPa. The PABA/BPA synthesis system has good decoration effect on HMCF.
