摘要:
采用静电力层层自组装技术在不同的基底上(玻璃,ITO导电玻璃)制备了多层氧化石墨(GO)/聚二烯丙基二甲基氯化铵(PDADMAC)复合超薄膜,并对其进行了还原处理。采用紫外-可见分光光度计(UV-Vis)、扫描电子显微镜(SEM)、X射线衍射仪(XRD)及Raman光谱仪对膜的结构进行了表征,研究了复合膜的电化学性质。结果发现,在一定浓度的PDADMAC和GO溶液中,交替沉浸较短的时间即可获得厚度均一、表面平整的复合超薄膜;对比不同电极的循环伏安曲线(CV)发现,超薄膜修饰工作电极较空白电极具有较强的电荷
Abstract:
The multi-layered GO/PDADMAC composite ultrathin films absorbed on different substrates(glass,ITO conductive glass) are prepared via an electrostatic layer-by-layer self-assembly technology.The ultrathin films are reduced by hydrazine solution.The microstructures of the self-assembled films are characterized by UV-Vis,SEM,XRD and Raman.In addition,the electrochemical behaviors of the films are also studied.The results show that the composite ultrathin films with smooth surface and uniform thickness can be obtained by immersing alternately the substrates into polyelectrolyte and GO colloid solutions with a definite concentration for a short time.Compared with the bare electrode,the electrodes modified with ultrathin films have higher capacity of electron transfer.
