中文摘要：
用乙烯基三甲氧基硅烷（VTMOS）对活性炭进行表面改性，并制成双电极扣式超级电容器，电解液为1mol／L Na2SO4。活性炭表面改性后，亲水官能团和比电容增加，扫描速度为1mV／s时的比电容为100F／g。活性炭比电容的增加与VTMOS的浓度有关，但VTMOS浓度超过0．75％，则粘结性过大，会堵塞活性炭表面的部分孔，降低超级电容器的性能。
英文摘要：
Activated carbon was surface modified with vinyltfimethoxysilane（VTMOS） and two-electrode button supercapacitor was prepared, 1 mol/L Na2SO4 was used as electrolyte. The hydrophilic radical and specific capacitance were increased after surface modifying of activated carbon. The specific capacitance at the scan speed of 1 mV/s was 100 F/g. The specific capacitance increasing was related with the concentration of VTMOS, but the cohesiveness would be too big if the concentration of VTMOS was higher than 0.75 %, some aperture on the surface of activated carbon would be blocked, the performance of supercapacitor decreased.
