Abstract: The present application relates to a method for preparing a thermosetting midsole using foamed particles with graphene oxide on surface. The method comprises: fusing the foamed particles with graphene oxide on surface with each other in a midsole mold under steam heating conditions to form the thermosetting midsole, wherein the body of the foamed particles with graphene oxide on surface is formed by mixing 60 wt % to 95 wt % thermoplastic polyurethane and 5 wt % to 40 wt % thermosetting polymer and foaming under non curing conditions. Thermosetting midsoles have high mechanical strength, good thermal stability, good chemical resistance, and good breathability, making them suitable for outdoor and extreme environments. The graphene oxide on the surface of the foamed particles prevents the foamed particles from fusing with other foamed particles where graphene is present, thus naturally leaving breathable channels.
