Multifaceted Janus Textile Simultaneously Achieving Self-Sustainable Thermal Management, Perception, and Protection

A shear-induced fibrillation strategy enables the continuous fabrication of microporous polytetrafluoroethylene fibers with nano-micro-fibrils with great porosity and strength. A multifaceted Janus design integrates spectral, electrical, and wetting dualities in one textile, realizing adaptive cooling/heating, self-powered sensing, and waterproof breathability without external energy. Comprehensive protection including electromagnetic interference shielding, UV resistance, flame retardancy, and chemical stability for self-sustainable, multifunctional, and comfortable wearables.
