Biochar/polypropylene composites (BPCs) have great potential in automobiles and building materials due to their ease of processing and light weight. However, the inferior interfacial bonding strength between biochar and polypropylene (PP) and flammability of PP often result in the weak mechanical properties and poor flame retardancy of BPCs, which limit the practical applications of BPCs. Herein, graphene oxide (GO) is used as an active interfacial modifier to prepare graphene-reed charcoal/polypropylene (G-RC/PP) composites. Benefiting from the mechanical interlocking effect formed by GO, the...
