The invention discloses a method for constructing a high-performance flexible interdigital
supercapacitor and an
integrated circuit by using
chlorine /
bromine doped graphene nanosheets, the ultra-stable
chlorine /
bromine doped graphene nanosheets are prepared by using a one-step
graphite electrocorrosion technology, and the
doping proportion of
chlorine /
bromine in the
graphene nanosheets can be adjusted by optimizing the concentration of
ammonium halide. And performing reduced pressure
filtration on the
graphene nanosheet aqueous solution to form a
graphene electrode pattern in a hollow area of the
metal template, transferring the
graphene electrode pattern to a high-molecular transparent substrate, and smearing an aqueous gel
electrolyte on the
electrode pattern to manufacture the series-parallel connection arbitrary combination
integrated circuit. The
surface charge distribution is improved by constructing a
nanosheet structure and introducing a carbon-
halogen bond, so that the
dispersity of graphene in water is remarkably improved, the stability of a graphene
aqueous solution is greatly improved, the stacking problem in the
service process of a
graphene electrode is avoided, the
cycling stability of the flexible interdigital
supercapacitor is improved, and the flexible interdigital
supercapacitor has a good application prospect. The constructed flexible interdigital supercapacitor has very good mechanical flexibility, flexible
assembly of an
integrated circuit can be realized by connecting the interdigital electrodes on the flexible substrate in series and in parallel, and power supply support is provided for various electronic devices. The whole construction process is simple and convenient, the
repeatability is good, and no
metal current collector, conductive agent or
polymer adhesive is used.
