Multi-responsive graphene/Ni based hyperbranched shape memory polyurethane composites |
| 초록 |
Magnetic Ni nanostructures grown on graphene nanosheets are of great interest for microwave and near infrared laser absorption. Using graphene/Ni as the nanofiller with hyperbranched polyurethane can stimulate the strain recovery in shape memory polymers more efficiently. In this study, graphene/Ni based hyperbranched polyurethane composites were fabricated to study the actuation behavior of composites which can respond to the microwave and laser irradiation. The hyperbranched polyurethane was synthesized based on poly(ε-caprolactone) as the switching segment. The actuation behaviors of HBPU/Gr/Ni composites such as shape recovery, shape fixity, actuation stress have been evaluated. The results of the study show that the graphene/Ni based polyurethane composites can be used as efficient multi-responsive actuators with enhanced mechanical properties. |
