摘要
采用两步合成法在玻碳电极表面上制备还原氧化石墨烯/聚(N-甲基硫堇)复合材料。采用紫外-可见光谱以及拉曼光谱证实了还原氧化石墨烯的表面和电子结构特征。在p H=1.0～12.0,0.2 mol/L PBS中,该复合材料表现出优异的电化学活性。复合材料的电化学活性比相应导电聚合物显著增强。这是由于还原氧化石墨烯与导电聚合物链中的芳香环之间的π-π相互作用,增强了聚合物的电化学活性以及导电能力引起的。
A reduced graphene oxide/poly(N-methylthinone) (rGO/PNMTh) composite was prepared by two-step synthesis process. Firstly, the reduced graphene oxide was obtained on the surface of a glass carbon electrode(GCE) via electrochemical reduction. Then, PNMTh was deposited on the rGO modified GCE to form the composite. UV-visible and Raman spectra were used to investigate surface morphology and structure of the rGO. Compared to PNMTh modified GCE, the obtained composite modified GCE showed better electrochemical activity in 0.2 mol/L PBS solution with different pH values (1.0~12.0). The π-π interaction between reduced graphene oxide and aromatic ring in conductive polymer chains enhanced the electrochemical activity of the polymer.
