A series of shape memory polyurethane (SMPU) were synthesized from poly(propylene glycol)(PPG) and diisocyanatodicyclohexylmethane(H12MDI) with the addition of graphene oxide which was chemically modified with allyl isocyanate. The properties of graphene oxide/polyurethane nanocomposite were characterized by mechanical, dynamic mechanical, thermal, electrical properties, and cyclic test. It was found that the shape memory effect of graphene oxide/polyurethane nanocomposite could be increased up to an iGO content of 1wt%, beyond that, most of the properties showed a decrease, due probably to the auto-inhibition of the allyl compounds. |
