▎ 摘 要
NOVELTY - Preparing graphene-modified polyvinyl alcohol (PVA) complex material comprises taking graphene as modifying agent, pre-plasticizing with starch, PVA, plasticizer and auxiliary agent, and then performing melt intercalation plasticizing extrusion at 145-220 degrees C to obtain final product. USE - The method is useful for preparing graphene-modified polyvinyl alcohol complex material. ADVANTAGE - The method: solves problem of yellowing occurs by polyvinyl alcohol; cannot processes carbonizing and decomposing processes; and is suitable for industrialized production.
