“…Bottlebrush polymers with densely grafted side chains have an extended backbone resulting from the repulsion between the side chains. – As compared with their linear analogues, one unique attribute of bottlebrush polymers is their significantly suppressed chain entanglements in the networks. – Thus, lightly cross-linking bottlebrush polymers provide a promising avenue for achieving the solvent-free supersoft materials. , Progress has been made in the development of bottlebrush polymer-based high-performance materials, especially those with self-healing capability, which can repeatedly repair mechanical damages and restore their functionality, resulting in the enhanced durability of the materials with prolonged service lifetime. – However, the preparation process of dynamically cross-linked bottlebrush polymers mostly involves the tedious functional end-group transformation of side chains and/or synthesis of small molecular cross-linkers. , Meanwhile, the resultant materials usually fulfill the self-healing behavior under elevated temperature, thereby limiting their applications in practice. , It should be further noted that the bioelectronic devices need to have direct contact with the human skin for effective signal transduction. – To the best of our knowledge, few of literature bottlebrush polymer-based supersoft materials possess adhesive capability and adhesive tapes or binding bandages are needed to fix the fabricated wearable sensors onto the human skin. , Apart from consideration of simplifying the operation process, it is also difficult for them to perfectly detect microstrains and feeble physiological signals . Therefore, it still remains a challenge to integrate the combination of excellent self-healing capability and adhesiveness into one bottlebrush polymer-based supersoft material, which is critical for the development of next-generation flexible electronic devices with high-quality and stable electrophysiological recordings.…”
