NOVELTY - Preparing antistatic expanded thermoplastic polyurethane (E-TPU) material involves dispersing graphene oxide in deionized water to obtain graphene oxide dispersion liquid. The graphene oxide dispersion liquid is dispersed in an organic solvent to obtain graphene oxide organic solution, where the weight ratio of organic solvent to deionized water is (1-9):1. A dipping treatment is carried out on the E-TPU granules by using the graphene oxide organic solution, and then drying treatment is carried out to obtain graphene oxide coated E-TPU granules. The graphene oxide coated E-TPU granules are completely dipped into a reducing agent solution for reduction treatment to obtain graphene coated E-TPU granule. A heating forming treatment is carried out on the graphene-coated E-TPU granules to obtain antistatic E-TPU material. USE - Method for preparing antistatic E-TPU material used as shoe material, packaging material, buffer gasket, vibration damping material, automobile interior trim and tire. ADVANTAGE - The method enables to prepare antistatic E-TPU material, which has excellent anti-static performance and stability. The method is simple and easy to carry out, and reduces the process difficulty, simplifies the process flow, production cost, and widely applied to antiistatic sole and anti-tire tire field. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an antistatic E-TPU material, which is obtained by filling the E-TPU particles and graphene in the form of a framework between the E-TPU particles.
