摘要: 以硫酸铜为主盐,以甲醛为还原剂,研究了连续碳纤维表面化学镀铜的工艺过程,包括pH值、络合剂质量浓度、添加剂质量浓度和还原剂体积分数对化学镀的影响.利用扫描电子显微镜(SEM)、能谱分析(EDS)检测了化学镀镀层的表面形貌、成分,利用溶解法测定了镀层厚度.结果表明,碳纤维镀前预处理非常重要,不仅能够防止“黑心”现象的出现,而且在碳纤维表面形成以Ag为中心的活性吸附区;在实验所得到的连续碳纤维镀铜工艺参数基础上进行碳纤维表面镀铜,镀层均匀,机械性能好,不易剥落,而且镀液稳定.

Abstract: The electroless copper plating process for continuous carbon fiber using CuSO4·5H2O as the main salt and formaldehyde as reducing agent was experimentally studied, including the effects of pH values and concentration of chelating agents, additives and reducing agent on the electroless plating process. The surface morphology and composition of coating were investigated by means of scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), and deposited the coating thickness was measurated by way of dissolution. The results indicated that the pretreatment of carbon fiber before plating is so important that it is not only able to prevent from the black core phenomenon but form an active absorption area with Ag as the center on the carbon fiber surface. With the process parameters got and optimized experimentally, the carbon fiber plated with copper shows homogeneous coating with favorable mechanical properties due to stable bath, such as the high bonding strength of coating.
