 "Prof. Le Yuan from Xihua University: Smart Multispectral Camouflage Textiles Inspired by Natural Leaves"

Challenge: Ideal optical camouflage technology requires simultaneous resistance to visible light, hyperspectral, and thermal infrared detection. However, developing smart camouflage materials with multispectral and all-weather stealth capabilities remains a significant challenge.

Method: Prof. Le Yuan's team at Xihua University, inspired by the transpiration effect and spectral characteristics of plant leaves, used electrospinning technology to prepare a biomimetic multilayer fiber fabric that successfully replicated the visible light, hyperspectral, and thermal infrared detection characteristics of natural leaves.

Innovation 1: Incorporating gradient porous structures into the multilayer fibers can simulate the directional water transport and transpiration cooling effects observed in plants. Compared with plants, this design achieved an evaporation rate of 0.84 kg m-2 h-1 while maintaining the maximum temperature difference within 1.01 °C.

Innovation 2: Precise pigment formulations and multilayer fiber structures accurately simulated the key spectral absorption and reflection mechanisms of natural leaves, matching visible and near-infrared spectral curves. The composite fibers also exhibited reversible color changes, mimicking different growth stages of leaves.
