High-strength self-healing polyurethane elastomers offer great potential across various application fields due to their excellent combination of toughness, elasticity, and autonomous damage repair. However, achieving an optimal balance between capabilities robust mechanical performance remains a significant challenge. In this study, we developed composite elastomer (PU-10% CNC) with enhanced properties by incorporating cellulose nanocrystals (CNCs) through solvent replacement process. This approach facilitates the uniform dispersion CNCs within elastomer, resulting in material that leverages abundant hydrogen-bonding π–π stacking interactions. Consequently, these supermolecular interactions collectively impart efficiency (91.8%) at room temperature. The introduction CNC, its numerous hydroxyl groups, formation multiple hydrogen bonds, acting as reinforcing points significantly improve tensile strength from 3.5 24.6 MPa while also enhancing resilience. Moreover, is fully recyclable via chemical routes, offering environmentally friendly solution for high-performance elastomers.

Flexible sensors are widely applied in the fields of electronic skins and wearable devices, yet it is still a big challenge to effectively prolong lifespan damaged reduce environmental pollution caused by discarded after updating upgrading. Herein, we proposed self-healing, degradable, biobased polyurethane elastomer for high-performance flexible pressure sensors. The synthesized using fatty diamine as chain extender possessed high tensile strength 13.25 MPa an elongation at break 830%, self-healing efficiency reached up 109.2%. Additionally, could be fully degraded within 7 days 1 mol L-1 NaOH solution with assistance ethanol. elastomer-based sensor hump-like microstructure was fabricated reduced graphene oxide conductive material via simple template method. showed sensitivity 9.448 kPa-1, large sensing range 0-300 kPa, short response/recovery time 40/80 ms, good stability 14,000 cycles. Moreover, utilized monitor different human motions, including muscle contraction, joint bending, swallowing, voice recognition, pulse beat. Importantly, even being severely damaged, able recover its function detecting motions. findings this research provide strategy sustainable development environmentally friendly functional elastomers
