摘　　要：通过热分解法制备Ti/RuO_(2)-HfO_(2)二元复合氧化物涂层,利用XRD对涂层组织结构进行表征,通过循环伏安和充放电曲线分析对涂层的超电容性质进行研究。实验结果表明,Hf的加入有利于非晶态组织的形成;随着Hf含量的增加,电极比电容呈现先增大后减小的变化趋势,当Hf含量为50%时,电极比电容最大;Hf具有促进电化学稳定性的作用。Ti/RuO_(2)-HfO_(2)composite oxide coating was prepared by thermal decomposition method and the microstructure of the coating was characterized by XRD.The supercapacitor properties of the coating were studied by cyclic voltammetry and charge-discharge curve.The results show that the addition of Hf is beneficial to the formation of amorphous structures.With the increase of Hf content,the specific capacitance of the electrode increases first and then decreases.When Hf content is 50%,the specific capacitance of the electrode reaches the maximum,and Hf has the effect of promoting electrochemical stability.
