Abstract Scope |
Ion-conductive self-healing (SH) hydrogels have received significant attention as biomaterials benefiting from the behavior of living tissue to broaden the design of health monitoring systems and soft robotics with autonomously SH capabilities. Herein, we propose a high-resolution 3D printing of ion-conductive SH hydrogel realized by micro-continuous liquid interface production (µCLIP). Once damage occurs, the 3D printed hydrogel fully recovers the mechanical properties after 12h at room temperature without external trigger. These novel hydrogels are designed with interpenetrating polymer networks (IPN) based on physical-crosslinked poly(vinyl alcohol) networks combined with chemical/ionic crosslinked networks formed by acrylic acid and ferric chloride. In addition, the ionic conductivity and high stretchability of the hydrogel enables strain and pressure sensing capabilities that could be applied as health monitoring system or soft robotics. This novel approach of high-resolution 3D printing of SH hydrogels in complex structures will provide a promising development of future biomedical devices. |
