Nankai University's Prof. Huang Yi et al.: Wearable Multifunctional Core-Shell Nanofiber Textiles Achieving Ultra-Wideband EMI Shielding and Infrared Stealth

Background: With the rapid development of wireless communication and infrared detection technologies, there is growing demand for large-scale, high-performance wearable textiles with electromagnetic interference (EMI) shielding and infrared stealth capabilities.

Approach: Prof. Huang Yi and Wang Yang from Nankai University employed a multistage low-temperature drying-assisted coaxial wet-spinning assembly strategy to fabricate meter-scale MXene/graphene oxide (MG)@Monstera nanocellulose (MC) core-shell nanofiber textiles, using MG as the conductive composite core and MC as the organic framework shell.

Innovation 1: These textiles demonstrate unprecedented ultra-wideband EMI shielding performance across gigahertz and terahertz frequencies, achieving optimal shielding effectiveness of 84 dB (8.2–26.5 GHz) and 85 dB (0.3–1.5 THz) at a mere 185 μm thickness.

Innovation 2: Benefiting from excellent thermal stability and low infrared emissivity, the textiles exhibit outstanding infrared stealth performance in near- and mid-infrared ranges. Additionally, they showcase superior dyeability, flame retardancy, Joule heating, and stress-sensing properties.
