Graphene‐Based Vitrimeric Ink with Self‐Healing Properties Enables Simple E‐Textile Triboelectric Coating Development

Abstract Advances in research in electronic textiles (E‐textiles) that primarily cater to wearable sensing technology have found amalgamation with self‐powered technology, especially with triboelectric nanogenerators (TENGs). However, developing E‐textiles with triboelectric properties involves a multi‐step process and a complex device structure, which is unsuitable for actual wearables. Also, the cellulose‐based fabrics with the highest wearability are unsuitable for TENG fabrication, limiting the usage to synthetic fabrics. Apart from wearability, self‐healing behavior is another significant property recently being looked upon for wearable sensors, providing long‐term functionality. Herein, a simple yet effective approach is proposed to develop dielectrically optimized coatings for developing cellulose fabric‐based self‐powered sensors by leveraging elastomers with tunable dielectric and other properties, otherwise catering to the domain of electronic skin separately. The record high output performance with a power density of 4.69 W m ⁻² accomplished using a single fabric layer with a thickness of 0.56 mm supports the amalgamation of dielectrically optimized elastomeric coatings with textiles for next‐generation self‐powered wearables. Also, the strategic utilization of dynamic covalent chemistry imparted self‐healing properties to the coating. This report provides a single‐step dip coating method for developing a self‐powered and self‐healable next‐generation E‐textile.
