中文摘要：
石墨棒经电化学剥离后,表面形成层数不等的石墨纳米片,它们彼此之间平行排列并垂直于碳基底构成一种开放式的2D纳米片阵列.以此作为基质,通过阳极氧化电化学沉积,使锰氧化物均匀地包覆在石墨纳米片表面,构成电化学活化石墨碳/锰氧化物复合膜.电化学测试表明,复合膜具有优良的超电容特性,在0.5mol.L-1 Na2SO4溶液中,扫描速率为5mV.s^-1,电位窗口为2.2V时,复合膜比电容高达7 750F.m^-2.
英文摘要：
After an electrochemical exfoliation,the surface on the graphite rod forms graphite nanosheets which layers are various in numbers and parallel to each other in space arrangements and perpendicular to the carbon substrate,resulting in an open 2D nanosheet array.Manganese oxide is uniformly loaded on the surface of graphite nanosheets by anodic oxidation electrochemical deposition.As a result,the electrochemical activated graphite carbon/manganese oxide composite membrane is obtained.Electrochemical measurements show that the composite membrane has excellent performance in ultra-capacitance and achieves a specific capacitance as high as 7 750 F·m^-2 within a potential window up to 2.2 V at the scan rate of 5 mV·s^-1 in 0.5 mol·L-1 Na2SO4.
