- Poly (N-isopropylacrylamide) (PNIPAm) hydrogels have been proposed for application as promising biomaterials and stimuli-responsive materials in biomedical fields, but their poor mechanical properties limited their development. Here we report that the mechanical properties of PNIPAm-clay nanocomposite hydrogels were enhanced significantly through in situ polymerization by addition of very low content of graphene oxide (GO). GO sheets were used as both the crosslinking agent and reinforcing agent. Compared to nanocomposite hydrogels without GO, a more than 200% increase in tensile strength and a nearly 400% improvement of Young’s modulus were achieved with the addition of 0.1 wt. % of GO, which suggests an excellent load transfer between the GO and hydrogel matrix.
