Abstract

ABSTRACT Next‐generation protection systems for medical, electronic‐device, and aerospace environments urgently require lightweight, flexible materials that protect the human body from multispectral radiation. However, simultaneously achieving strong broadband attenuation and effective thermal protection within ultralight fibrous structures remains a significant challenge. Here, a flexible ultralight core/double‐shell Bi/W 18 O 49 /GO/PAN fiber composite with thermal protection capability is developed. By constructing high‐Z W 18 O 49 /Bi double shells on electrospun GO/PAN fiber cores, the composite exhibits enhanced photon absorption together with efficient multispectral radiation blocking. It features an ultralow density of 0.40 g cm −3 , with
