Research on electrochemical behaviors of diamond-like carbon film electrodes

类金刚石(DLC)薄膜以其优异的物理化学性能引起了人们的研究兴趣。导电的DLC薄膜可以作为电极材料并表现出宽的电势窗口,低的背景电流,良好的电化学活性,表面易修饰,从而有望用于生物电分析及污水检测等方面。从薄膜的制备、薄膜与基底界面、薄膜表面修饰等几个方面综述了DLC薄膜电极的制备技术和电化学行为研究,并对其应用前景进行展望。

Diamond-like carbon （DLC） films have attracted considerable interest for their extreme physical and chemical properties. Conductive DLC films represent wide potential window, low background current, excellent electrochemical activity, easy modification of electrode surface, demonstrating the feasibility of employment as electrode materials for biological electroanalysis and wastewater treatment. In this paper the deposition technology and research on electrochemical behaviors of DLC films were reviewed, and a prospect was given to the application of the materials in broader fields.
