摘要
碳纤维是最重要的复合材料增强体之一,而碳纳米管比碳纤维具有更好的力学性能,对他们的表面改性将会对复合材料性能有很大影响.试验实现了一种对碳纤维和碳纳米管通用的化学镀镍工艺.通过对基体较好的预处理,在基体上成功地完成了化学镀镍并且较好的控制了镀层成分.同时还探讨了施镀温度、pH值和搅拌方式等对镀层的影响,试验发现pH值控制在9～10之间,温度控制在70 ℃附近并采用氮气搅拌可以获得较满意的施镀效果.
Surface coating is widely used on carbon fibres and carbon nanotubes when fabricating high-quality fiber-reinforced metallic composites. A novel method of electroless nickel plating on surface of both carbon fibres and carbon nanotubes was developed. Nickel was successfully deposited on the surfaces of carbon fibre and nanotube after the elaborate pretreatment. The optimal formula and experimental conditions for electroless nickel plating were obtained. Moreover, the influence of the plating temperature, pH value and mixing method on the coating film were discussed.
