Regulating the Dielectric Behavior of Conductive Polymers Through Vapor Phase Infiltration for Tunable Microwave Absorption

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Vapor phase infiltration (VPI) enables atomic‐level dielectric regulation in conductive polymer foams. The VPI‐treated foam exhibits enhanced absorption efficiency per unit thickness (~2.6 times), dynamic frequency tunability (94.5% coverage in 2–18 GHz), and on/off switching ability while retaining performance under acid/alkali exposure and repeated ...
