ABSTRACT Designing electromagnetic wave‐absorbing materials (EMAs) with adjustable performance is crucial for adapting to constantly changing electromagnetic environments. Herein, a flexible polyvinyl alcohol/polyaniline (PPA) aerogel was fabricated through a one‐step process combining unidirectiona...
