Microwave-Assisted Reversible Coordination-Mediated Polymerization for Self-Healing Hybrid Materials: RGO@PDA Simultaneous as Catalyst and Nanocomposites in One-Pot

摘要

In this article, polydopamine (PDA) is efficiently adhered on the surface of graphene oxide (GO) by mussel-inspired chemistry. The obtained reduced GO/PDA (RGO@PDA) nanocomposites are used for catalyzing reversible coordination-mediated polymerization under microwave radiation. Welldefined and iodine-terminated polyacrylonitrile-co-poly(n-butyl acrylate) (PAN-co-PnBA) is successfully fabricated by using RGO@PDA nanocomposites as catalysts. Importantly, green and novel strategy of PAN-co-PnBA-type self-healing nanocomposite materials is further fabricated with RGO@PDA as additive after polymerization as catalyst in one-pot. As a reinforcement agent, RGO@PDA can also improve the mechanical and self-healing properties of hybrid materials, which opens up a novel and green methodology for the preparation of self-healing hybrid materials.
