Abstract 4D printing enables 3D-printed structures to morph upon being exposed to external stimuli. Amongst all engineering materials, polymers show high 3D printability as well as tunability regarding to its morphing behaviour and functionalities. Generally, composites with epoxy as matrix shows high modulus and strength, whereas its mechanically brittle property makes it difficult to be morphed and snapped-through at room temperature, thereby limiting its 4D printability and its functionality. On the other, Polydimethylsiloxane (PDMS), as an elastomer, shows its high elasticity and stretchability, yet its printability and mechanical properties of its printed composites still need improving… More >
