【摘要】：采用電鍍法制備了鍍銅短碳纖維,借助掃描電鏡(SEM)對鍍層微觀形貌以及鍍層厚度進行了微觀表征,并利用X射線光電子能譜(XPS)分析技術對鍍層的化學成分和鍍層中主要元素化合價態(tài)進行了分析。結果表明:經過預處理的碳纖維表面變得粗糙,有很多親水性含氧官能團;電鍍電壓2 V,電鍍時間20 min,電鍍溫度30℃時,可獲厚度約1.2μm、短碳纖維端頭被鍍層緊緊包裹的均勻電鍍層;鍍層中間大部分銅以單質形式存在,表面鍍銅層被氧化成氧化銅,鍍層仿形生成,與碳纖維形成一個緊密的鑲嵌體系。
[Abstract]:Copper coated short carbon fiber was prepared by electroplating. The microstructure and thickness of the coating were characterized by scanning electron microscopy (SEM). The chemical composition of the coating and the valence states of the main elements in the coating were analyzed by X-ray photoelectron spectroscopy (XPS). The results show that the surface of the pretreated carbon fiber becomes rough and has many hydrophilic oxygen functional groups, the electroplating voltage is 2 V, the electroplating time is 20 min, and the electroplating temperature is 30 鈩，
