碳纤维表面连续电镀镍的研究

Continuous Nickel-plating on Carbon Fiber Surface

本研究对碳纤维表面进行了连续电镀镍试验，首先对碳纤维预处理，依次经400oC灼烧30min、丙酮浸泡30min、氢氧化钠溶液中煮沸15min、硝酸中浸泡30min后烘干。随后研究了预处理后的碳纤维连续电镀镍工艺，连续电镀镍实验条件为：电流为1．0A、温度为35℃、pH值4—5，电镀液的配方为硫酸镍（260g／L）和氯化镍（40e,／L）、缓冲剂40g／L硼酸、润湿剂0．2g／L十二烷基硫酸钠。碳纤维连续电镀镍后，通过扫描电子显微镜和能谱仪的测试，结果表明：处理后的碳纤维上沉积了一层连续、致密镍层。

Continuous nickel-plating on carbon fiber surface has been studied in this paper. Firstly, carbon fiber was pre-treated follow by ignition at 400 ℃ for 30 min, soaking in acetone for 30min, boiling in sodium hydroxide solution for 15min, soaking in nitric acid for 30min. And then, continuous nickel-plating was proceeded by controlling the current, temperature and pH value. The best experimental conditions are as follows： 1.0 A for current, 35 ℃ for temperature, 4 - 5 for pH, the formula of plating solution is ： 260 g/L for NiSO4, 40 g/L for NiC12,40 g/L for H3BO3, 0.2 g/L for C12H.3OSO3Na. The results show that the continuous and dense nickel layer is deposited on carbon fiber surface through the test of SEM and EDS.
