Bioinspired Layered-Gradient Nanocomposites for Intelligent Electromagnetic Skins with GHz-THz Wave Absorption, Shielding, and Solvent-Driven Actuation

The development of intelligent electromagnetic skins demands scalable films integrating gigahertz (GHz)-terahertz (THz) wave absorption, electromagnetic interference (EMI) shielding, and programmable actuation. Here, we report a bioinspired bamboo-like layered-gradient system fabricated via scalable vacuum filtration, in which two types of films are constructed with distinct functionalities: a low-poly(3,4-ethylenedioxythiophene) (PEDOT) content film for microwave absorption and a high PEDOT con
