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.
