Abstract Thermally driven membrane distillation (TDMD) has emerged as a promising seawater desalination technology to address the freshwater shortage and energy crisis. However, conventional “bulk‐heating” technologies results in serious temperature polarization phenomenon, hindering efficient utilization of energy. Here, an innovative hydroxylated CNTs‐engineered polyvinylidene fluoride (H‐CNT@PVDF) is proposed which imparts efficient, localized photo‐/electro‐thermal self‐heating effect. To prevent heat loss from layer bulk water, transparent silica aerogel microspheres (SAM) deposited on H‐CNT layer, achieving excellent self‐insulating The SAM@H‐CNT@PVDF Janus achieves 486% increase MD flux compared with membrane. Although SAM only account for 3.8% membrane, thermal resistance increases, unexpectedly, by more than 600%, allows most be concentrated at used evaporation. overall energy‐to‐water efficiency reach 94.5%, outperforming state‐of‐the‐art devices.

Flexible water management textiles can achieve effective liquid-thermal evaporation by harvesting exogenous heat. However, existing exhibit limited capacity and cooling efficiency due to undesirable water-heat transport structures. Inspired the human skin's efficient heat dissipation mechanism through sweat evaporation, we propose an integrated multiheat source module concept. The interpenetrating structure of disperse fibers porous conductive pores endows this material with synergistically enhanced radial diffusion rate thermal energy transmission efficiency, as validated infrared droplet tests solute models.
