Abstract

image

Graphene oxide (GO)/polyacrylamide (PAM) hydrogels with highly elastic and superstretchable mechanical behavior is fabricated by the synergistic effects of a Ca2+-induced GO crosslinking network, chemically crosslinked PAM network, and entanglements between these networks via hydrogen-bonding interactions. This new nanocomposite material may broaden the applications of hydrogels in the biomedical field and take us closer to artificial biotissues.
