Textiles incorporated with phase changing materials (PCMs) can bridge the supply and demand for energy by absorbing and releasing latent heat. The integration of solar heating and the Joule heating function supplies multidriving resources, facilitates energy charging and storage, and expands the service time and application scenarios. Researchers in Japan have developed a fibrous membrane-based textile by designing the hierarchical core–sheath fiber structure for trimode thermal management. Coaxial electrospinning allows an effective encapsulation of PCMs, with high heat enthalpy density enabling the membrane to buffer drastic temperature changes in the clothing microclimate. The favorable photothermal conversion performance renders the membrane with the high saturated temperature of 70.5 °C, benefiting from the synergistic effect of multiple light harvesters. A conductive coating endows the composite membrane with electrothermal conversion performance, reaching a saturated temperature of 73.8 °C (4.2 V). The flexible fibrous membranes can be used for all-day, energy-saving, and wearable individual thermal management applications…read more. TECHNICAL ARTICLE
