▎ 摘　　要

NOVELTY - Foamed sole comprises a thin reducing graphene oxide layer provided on the surface of a reducing graphene oxide ethylene vinyl acetate (EVA) composite layer. The reducing graphene oxide of the thin reducing graphene oxide layer and the EVA in the reducing graphene oxide EVA composite layer are bonded through a stable covalent bond. The reducing graphene oxide content in the reducing graphene oxide EVA composite layer is gradually reduced from up to down. USE - Used as foamed sole. ADVANTAGE - The sole: has good antibacterial function; ensures surface antibacterial function layer attached firmly; and is not easy to peel off. DETAILED DESCRIPTION - INDEPENDENT CLAIMs are also included for: (1) preparing foamed sole comprising (a) preparing EVA particles, (b) preparing reducing graphene oxide EVA particles, (c) mixing the EVA particles prepared in the step (a) and the reducing graphene oxide EVA particles prepared in the step (b), and preparing the foaming material by the injection technique; and (2) shoe made with the foamed sole, prepared by above method.
