电化学沉积石墨烯/DLC复合薄膜的腐蚀性能研究

Research on Corrosion Resistance of Graphene/DLC Film Prepared by Electrodeposition

阐述了液相电化学沉积法制备类金刚石碳基(DLC)复合薄膜,以无水甲醇为碳源,自制的石墨烯为掺杂剂,在单晶硅基底上电化学沉积制备得到RGO/DLC复合薄膜,利用TEM、AFM、Raman、XPS等表征手段对复合薄膜的表面形貌及微观结构进行了研究,发现石墨烯在DLC复合薄膜中均匀分散,掺杂结果表明所得薄膜主要成分为C、O;电化学腐蚀测试结果表明所得薄膜在Na Cl溶液中具有较好的抗腐蚀性能。

Preparation of diamond-like carbon （DLC） composite films by liquid electrodeposition was expounded. GO-DLC composite film was prepared by electrochemical deposition with anhydrous methanol as a carbon source and graphene as a dopant on the single crystal silicon substrate. Its surface morphology and microstructure were studied by TEM, AFM, Raman, and XPS.The results show that the grapheme can be uniformly dispersed on the composite DLC film. The doped results show that C and O are the major components in obtained films. Electrochemical corrosion test results show that the film has good corrosion resistance in NaC1 solution.
