Preliminary scope of work |
Two-way shape memory effect is the material's ability to change its shape through an actuating by temperature change or electrical current. This allows the structure to change its shape without additional actuators [1]. There are few known approaches that can achieve inducing two-way shape memory effect [1-2]. The approach studied in this thesis is through the creation of Nitinol-polymer composite. Nitinol is a widely one-way shape memory alloy. This material can return to its original shape after external load has been released. In previous studies the combination with polymer has been shown to induce a two-way shape memory capability in the composite [3]. However, these composites suffer from degrading interfacial adhesion with repeated actuations. This thesis explores alternative techniques of creating two-way shape memory composite with focus on enhancing interfacial adhesion. |
