A novel water-induced shape memory nanocomposites were prepared by introducing graphene oxide (GO), which was based on microcrystalline cellulose nanofibers (MSF-g-COOH) extracting from sisal fibers. The results showed that the water-induced shape memory properties of MSF-g-COOH were significantly improved by the strong hydrogen bonding interaction between MSF-g-COOH and GO, It leads to some additional...
Significant reinforcement of polyurethane/epoxy (PU/EP) composites in situ synthesized on the graphene oxide nanosheets (GONS) is reported for the first time. Firstly, the PU prepolymer was in situ synthesized on the GONS. Then, the EP and a curing agent were added to prepare the PU/graphene oxide/EP (PU/GO/EP) nanocomposites. Morphologic study shows that, due to the formation of chemical bonding,...
