Positively charged cyano-bridged CoNi coordination polymer flakes (CoNi-CP) are mixed with graphene (G) suspension with negatively charged surface. Due to effective electrostatic interaction, both the materials are hybridized to form CoNi-CP/G composite. The as-prepared CoNi-CP/G composite is thermally treated in air, to remove the organic components without affecting the integrity of the parent G sheets. Through the thermal treatment, the CoNi-CP flakes wrapped into G sheets are converted to NiCo oxide, resulting in a new composite consisting of NiCo oxide flakes and G sheets. The NiCo-oxide/G composite shows the high specific capacitance (? 199 F g-1) at 5 mV/s, and features the good capacitance retention of ?68% at 100 mV(? 135 F g ?1 ). ? 2018 Wiley-VCH Verlag GmbH & Co.
