Self-Healing MXene/Polymer Composites for Healthcare Applications

Healthcare devices play an important role in the diagnosis, treatment, and monitoring of patients. MXene, as a new member of the two-dimensional materials family, has characteristic conductivity, hydrophilicity, biocompatibility, and antibacterial ability, which makes it suitable for fabricating healthcare devices. By combining MXene with self-healing polymers, durable and self-healing healthcare devices that are resistant to mechanical damage during dynamic work can be achieved. Thanks to the dual biocompatibility of MXene and polymers, the self-healing MXene/polymer composites have the functions of sensing and self-healing in vivo and in vitro, serving as a basis for modern healthcare devices. Herein, we summarize the recent progress of using MXene/polymer composites to fabricate skin-friendly sensors with self-healing capability: universal strategies for fabricating self-healing MXene sensors and their fundamental performance are discussed, and biomedical healthcare applications are demonstrated. This review aims to provide a reference for MXene-based self-healing healthcare electronics and facilitate further efforts in the innovation of modern biomedical devices.
