Confined Hydrothermal Assembly of Hierarchical Porous MXene/RGO Composite Fibers with Enhanced Oxidation Resistance for High-Performance Wearable Supercapacitors.

Summary: Imagine a future where your jacket or shirt could charge your smartphone. Scientists are getting closer to this reality by improving "MXene fibers," a material that conducts electricity incredibly well and can be woven into fabric. Until now, these fibers had a major weakness: they would "rust" (oxidize) easily and clump together, losing their ability to store energy.

In a new breakthrough, researchers created a "shielded" version of these fibers using a specialized pressure-cooking method (hydrothermal assembly). They combined MXene with graphene (RGO) and a chemical called thiourea. The graphene acts like a physical barrier to stop the clumping, while the thiourea acts as a chemical guard against rust. The result is a highly conductive, flexible fiber that is durable enough for next-generation wearable electronics.
