Recently, some significant researches have been focused on polymeric gel materials crosslinked by reversible interactions which can provide stimuli-responsive and self-healing properties. In this work, we present both physical and chemical hydrogels based on biocompatible 3,4-dihydroxyphenethylamine(dopamine)-conjugated polyaspartamide which was developed as a mussel-mimetic functional polymer. The responsive interaction between catechol groups and metal ions (B, Fe, Al, etc) or graphene oxide(GO) can make secondary bonding to the existing gel network to strengthen the hydrogel, as well to provide self-healing property. |
