Herein, we propose a facile method to synthesize self-adhesive organosilicon elastomers with high mechanical strength, flexibility, and self-healing performance by designing dynamic networks.

The optimized organosilicon elastomers exhibit exceptional stretchability and mechanical properties, including an elongation at break of ∼5600 %, high strength (2.2 MPa), and toughness (54.38 MJ/m<sup>3</sup>), outperforming traditional organosilicon elastomers.
