Stable, Highly Conductive, and Strain-Insensitive Supramolecular Elastomer Composite for Printable Self-Healing Soft Electronics.

ABSTRACT: Stretchable and self-healing soft conductive materials are essential for soft electronics, robotics, wearables, and bioelectronics. However, achieving a single material that simultaneously offers high and stable conductivity, minimal resistance changes under extreme stretching, high-resolution universal printability, autonomous self-healing, and pressure-sensitive adhesive properties for direct bonding of surface-mountable components remains challenging. Here, a printable ink composed of liquid metal microparticles and carboxylic acid-functionalized carbon nanotubes, blended into a bimodal supramolecular elastomer matrix is introduced. After photothermal activation, the material is capable of reorganizing conductive pathways and achieves a high conductivity (> 20000 S·cm^-1 under
