Bioinspired multifunctional MXene-decorated textile for thermal management, durable self-cleaning, bio-protection and wearable strain sensor

Textile-based wearable electronic devices have gained significant attention due to their promising applications in personal thermal management, human healthcare monitoring, and human motion detection. Herein, a multifunctional MXene-decorated textile has been fabricated as a promising wearable electronic textile for thermal management, durable self-cleaning, bio-protection and wearable strain sensor. In this study, Ti 3 C 2 T x MXene nanosheets , which are followed by surface engineering with mussel-inspired polydopamine coatings and hydrophobic octadecyl trimethoxysilane, are chosen as active materials for constructing multifunctional MXene-decorated textile. Thus, the multifunctional MXene-decorated textile (Cotton@ODMX) is fabricated by spray-coating the hydrophobic MXene-based composites (ODMX) onto the surface of the cotton textile. Such a Cotton@ODMX epitomizes a highly innovative electronic textile that not only retains the flexibility of the original textile, but also possesses remarkable superhydrophobic properties, outstanding photothermal conversion performance, photothermal self-healing capabilities, environmental stability and exceptional photothermal sterilization capabilities. More importantly, Cotton@ODMX is demonstrated to serve as a wearable strain sensor to monitor fundamental human movements, thus highlighting its impressive sensing capabilities. This work offers valuable insights for the development of multifunctional, flexible and wearable electronic devices with promising potential in personal thermal management, human healthcare monitoring, and human motion detection.
