Controllable Stretchable, Conductive, and Adhesive Based on Visible Light Triggered Swelling-responsive Artificial Skin Hydrogel |
| 초록 |
Hydrogel possessing outstanding mechanical and electronic properties under visible light stimuli is critical for wide array applications such as robotics and smart wearable devices. The controllable swelling-responsive artificial skin hydrogel was designed based on TiO2-polydopamine-perfluorosilica carbon dot (CD) conjugated chitosan-polyvinyl alcohol (PVA) by adopting Michael addition and Schiff Base mechanism followed by an additional adhesive additive to improve the attach-ability of the hydrogel to the surface. The shift of hydrophilicity and dimensional changes on the surface affected the swelling performance that allow water penetration into hydrogel, resulting in significant changes in elasticity, electronic response, and adhesive behavior. Furthermore, the hydrogel demonstrated resistive and capacitive reversibility along with finger bending motion at different angles, indicating its capability as a promising candidate for artificial skin research. |
