AI Technical Summary
Existing self-healing materials, particularly those in the extrinsic system, are unsuitable for soft electronics due to impaired electrical and mechanical properties, premature leakage, and lack of reprocessability and recyclability, and often require external stimuli or repeated refilling, making them impractical for applications like skin-mounted devices.
A method for manufacturing an intrinsically self-healing elastomer using an interpenetrating network of polyborosiloxane and polydimethylsiloxane, incorporating boron trioxide nanoparticles, which allows for autonomous healing without external stimuli, improved mechanical properties, and transparency, suitable for soft electronics.
The elastomer exhibits excellent elasticity, autonomous self-healing efficiency, moisture barrier ability, and transparency, maintaining self-healing capabilities in challenging conditions, and supports a wide range of industrial applications including soft and printed electronics.
