Preparation method of intercalated graphene blended polyurethane open-cell sponge for adsorption

The invention relates to the field of graphene application, and particularly discloses a preparation method of intercalated graphene blended polyurethane open-pore sponge for adsorption, the method comprises the following steps: S1, preparation of intercalated graphene nanosheets: preparing graphite oxide by using crystalline flake graphite, and then preparing the intercalated graphene nanosheets by hydrothermal intercalation of dihydric alcohol; s2, preparing a graphene dispersion liquid; s3, preparation of foamed sponge: mixing and foaming the graphene dispersion liquid prepared in S2, an auxiliary agent and isocyanate through a pump to obtain the foamed sponge; s4, preparation of a sponge finished product: firstly cooling the foamed sponge obtained in S3, then curing and shaping, and then blasting, cutting, drying and deodorizing to obtain the sponge finished product, namely the intercalated graphene blended polyurethane open-cell sponge. According to the present invention, the requirements of large-scale
