Reprocessable and healable ethylene copolymer/f-rGO nanocomposites crosslinked by Diels-Alder adducts with infrared- and thermo-responsive behavior

In this work, multi-stimuli responsive nanocomposites with recyclability and rapid healability features were developed by simultaneous incorporation of thermo-reversible DA bonds and functionalized reduced graphene oxide (f-rGO) into ethylene copolymer (G-PE). Reversible formation-dissociation of DA...
