다국어 초록 (Multilingual Abstract)

Responsive and self-healing materials have a wide range of potential uses, and some significant researches have been focused on hydrogel materials crosslinked by reversible coordination bonding which can provide stimuli-responsive and self-healing properties. In this work, we present hydrogels based on biocompatible 3,4-dihydroxyphenethylamine(dopamine)-conjugated polyaspartamide, which was developed as a mussel-mimic functional poly(amino acid). The pH-responsive interaction between catechol groups and metal ion (e.g. Fe+3) or boron (B) make secondary bonding to the existing gel network to strengthen the hydrogel, as well as to provide self-healing property. Incorporation of graphene oxide (GO) within the gel was also attempted to identify a tough nanocomposite hydrogel which might show a good self-healing ability.
