Shape Memory Graphene Nanocomposites—Fundamentals, Properties, and Significance

Shape memory nanocomposites are excellent smart materials which can switch between a variable temporary shape and their original upon exposure to external stimuli such as heat, light, electricity, magnetic fields, moisture, chemicals, pH, etc. Numerous nanofillers have been introduced in polymers carbon nanotubes, graphene, nanodiamonds, nanofibers, Among nanocarbons, graphene has attracted research interest for the development of polymer/graphene nanocomposites. Graphene is unique one-atom-thick two-dimensional nanosheet sp2-hybridized atoms. used an effective nanofiller polymeric owing its remarkable electrical conductivity, flexibility, strength, heat stability. Thermoplastics well thermoset matrices form nanomaterials with nanofiller. In nanocomposites, fixed above transition temperature then transformed through stimulus. The inclusion cause fast switching shape. Fine dispersion, matrix–nanofiller interactions, compatible interface lead high-performance graphene-derived Consequently, this review focuses on important class graphene-based fabrication, physical properties, actuation discussed. stimuli-responsive mostly revealed heat-, electricity-, light-induced effects. enhanced physical/covalent linking, recovery, fixity, crystallization effects polymers. Furthermore, potential applications these observed aerospace/automobile industries, civil engineering, biomaterials.
