23 Jul Preparation method of anti-abalone shell structure high-toughness epoxy-graphene nano composite material
Abstract
The invention relates to a preparation method of a high-toughness epoxy-graphene nano composite material with an anti-abalone shell structure. By means of an ice template method, graphene oxide is used as an element material; according to the preparation method, a layered graphene oxide-sodium carboxymethyl cellulose three-dimensional skeleton is constructed, after the skeleton is subjected to thermal reduction, an epoxy prepolymer is infiltrated and cured, so that the bionic layered epoxy-graphene nano composite material is constructed, wherein the weight content of epoxy resin is greater than 95 wt%, and the weight content of the graphene skeleton does not exceed 5 wt%. Different from a traditional abalone shell imitating composite material, the abalone shell imitating composite material is called as an anti-abalone shell structure of which the organic matter content is far higher than that of an inorganic reinforcing material, and has excellent fracture toughness and a crack self-monitoring function. The epoxy-graphene nano composite material with the anti-abalone shell structure has a wide application prospect in the fields of aerospace, energy storage, tissue engineering andthe like.
