Electrospinning Machine| Temperature-Responsive Resonator Metafabrics for SelfAdaptive Thermoregulation

Prof. Wang Hongzhi et al. at Donghua University in Adv. Funct. Mater. (IF 18.5): Smart Metafabric with Temperature-Adaptive Multi-Fiber Resonator Structure

Challenge: Against the backdrop of global energy constraints and rapid development of flexible electronics, achieving efficient, zero-energy temperature regulation has become a critical challenge.

Approach: Prof. Wang Hongzhi from Donghua University collaborated with Researcher Zhao Shanyu from Swiss Federal Laboratories for Materials Science and Technology (EMPA) to develop a smart metafabric with temperature-adaptive multi-fiber resonator structure that enables self-adaptive thermal regulation in both hot and cold environments without external energy consumption.

Innovation 1: This work first reports a temperature-responsive metafabric with nanofiber resonators showing extraordinary Δε of 0.69 (ε=0.85 at high temperature and ε=0.16 at low temperature), simultaneously modulating both visible (VIS) and near-infrared (NIR) sunlight for self-adaptive temperature regulation.

Innovation 2: Compared with single-fiber resonators, the multi-fiber resonator system achieves 5.6× greater Δε and 3.8× broader spectral coverage. This passive VIS-NIR-LWIR adaptive metafabric provides an eco-friendly solution for electronics temperature regulation under fluctuating conditions.
