▎ 摘　　要

NOVELTY - Preparing graphene functionalized polypropylene corrugated pipe comprises (i) preparing graphene by improved Hummers method, (ii) treating graphene oxide with 2-bromoisobutyryl bromide to obtain graphene oxide-bromine, (iii) adding p-phenylenediamine and aqueous ammonia to obtain graphene oxide-phenylenediamine, (iv) adding graphene oxide-phenylenediamine to maleic anhydride grafted polypropylene to obtain graft modified functionalized graphene oxide, (v) mixing and grafting functionalized graphene oxide and polypropylene to obtain graphene/polypropylene composite material, and (vi) graphene/polypropylene composite material with material as masterbatch material to obtain final product. USE - The method is useful for preparing graphene functionalized polypropylene corrugated pipe. ADVANTAGE - The product: has high rigidity.
