Researchers reviewed hundreds of studies to evaluate MXenes, a class of two-dimensional, microscopic metal-based materials, and their role in smart textiles. MXenes can be coated or printed onto fabrics to give new electrical and chemical functions while keeping the textiles flexible and lightweight. The review appears in ACS Omega; Joyjit Ghosh, a doctoral student at the University of Georgia’s College of Family and Consumer Sciences, is the corresponding author.
MXene-based textiles can monitor body temperature, blood pressure and heart rate, and they can track movement in real time. In healthcare these fabrics could let clinicians monitor patients remotely and receive alerts for irregular vitals. Fabrics that react to bodily changes could also help regulate body temperature, and the materials’ antimicrobial traits may reduce bacterial growth on medical textiles.
Smart textiles can harvest solar energy and include thin energy-harvesting and storage layers, functioning like a flexible, wearable power bank that might charge a phone or even a laptop in the near future. The review also highlights limits: MXenes oxidize when exposed to oxygen or water and can lose performance after multiple washings, and their production relies on non-sustainable, metal-based compounds and energy-intensive processing. Ghosh and his lab are working to reduce oxidation and to prepare MXenes using more sustainable, biodegradable materials.
