【 摘 要 】

Here, we successfully prepare graphene/poly (diallyldimethylammonium chloride)-poly (styrene sulfonate) (G/PDADMAC-PSS) polyelectrolyte composites by simple mixing method. The effect of NaCl adding at 2, 4, 6, 8 and 10 % wt. on the sizing of polyelectrolyte composites (PECs) is investigated. The concentration of NaCl ion plays an important role in size control by the formation of the primary polyelectrolyte composites and following by the agglomeration itself. The electrochemical properties are evaluated by cyclic voltammetry demonstrating that G/PDADMAC-PSS PECs at 8 %wt. can yield the highest specific capacitance of 68 m F.cm-2; at 10 mV sec-1
