Graphite oxide was exfoliated and dispersed in propylene carbonate (PC) by bath sonication. Heating the graphene oxide suspensions at 150 degrees C significantly reduced the graphene oxide platelets; paper samples comprising such reduced graphene oxide platelets had an electrical conductivity of 5230 S/m. By adding tetraethylammonium tetrafluoroborate (TEA BF(4)) to the reduced graphene oxide/PC slurry and making a two-cell ultracapacitor, specific capacitance values of about 120 F/g were obtained.
氧化石墨通过浴式超声剥离并分散在碳酸丙烯酯（PC）中。将氧化石墨烯悬浮液加热至 150 摄氏度可显著减小氧化石墨烯片层的尺寸；由这种还原氧化石墨烯片层组成的纸张样品具有 5230 S/m 的电导率。通过向还原氧化石墨烯/PC 浆料中添加四乙铵四氟硼酸（TEA BF(4))并制作双电层超级电容器，可获得约 120 F/g 的比电容值。
