Preparation method of composite sponge with graphene and three-dimensional polypyrrole skeleton

Abstract

The invention provides a preparation method of a composite sponge with a graphene and three-dimensional polypyrrole skeleton. The method comprises the following steps of first, washing nickel foam clean with absolute ethyl alcohol, acetone and a deionized water solution, and drying the washed nickel foam for use; second, cutting the nickel foam which is washed clean to the needed size, placing thenickel foam into a 0.3 M NaClO4 solution containing 5% (volume ratio) of a pyrrole solution to use the nickel foam as a working electrode, using a platinum wire as a counter electrode, and using a calomel electrode as a reference electrode; third, taking out a black complex of polypyrrole and nickel foam subjected to electroplating, washing the complex in deionized water to remove unoxidized pyrrole monomers on the surface of the complex, and placing the complex which is washed clean into a 1 M FeCl3 solution to be etched; and fourth, air-drying the complex at the room temperature after washing the complex in deionized water, and obtaining the three-dimensional polypyrrole skeleton. The preparation method of the composite sponge with the graphene and three-dimensional polypyrrole skeletonis easy to operate.

Description

Technical field [0001] The invention belongs to the field of chemistry, and particularly relates to a preparation method of graphene-three-dimensional polypyrrole skeleton composite sponge. Background technique [0002] Graphene nanosheets have a two-dimensional planar structure. After the introduction of one-dimensional (such as carbon nanotubes) or two-dimensional (such as molybdenum disulfide) nanomaterials with them, due to the van der Waals force and π-π force between molecules For reasons such as these, these one-dimensional or two-dimensional nanomaterials will be adsorbed with graphene nanosheets to form graphene composite nanosheets; through the synergy between various materials, graphene composite nanosheets have better Its mechanical properties can be assembled into a three-dimensional structure to obtain a multifunctional graphene composite sponge.
