Synthetic morphing composites can change their shape actively in response to triggers and have great potential for applications as sensors, soft actuators, in robotics and biomedicine. In this study, graphene-reinforced chitosan/polydimethylsiloxane bi-layered morphing composites are developed, leveraging their differential coefficient of thermal expansion to enable different volume changes within each layer. UV photo-polymerisation/crosslinking serves to improve the bi-layer interface and prevent delamination during morphing. It is possible to design accurate patterned bi-layered structures with the aid of mask-less dynamic light photolithography (DLP). Upon activation by thermal triggers, the bi-layered composite achieves rapid, reversible and multi-repeatable morphing. A finite element model is developed to simulate the deflection of the sample due to anisotropic thermal expansion of the bi-layer. The model can predict the deflection of the bi-layered composite with a relative error of 3.3 % in comparison to experimental results.
