Electrically conductive conjugate microporous polymers (CMPs) via confined polymerization of pyrrole for electromagnetic wave absorption

Abstract Endowing conjugate microporous polymers (CMPs) with appropriate electrical conductivity greatly expands the application scope of CMPs, especially in electronic-related applications. In this paper, we report a strategy to prepare electrically conductive CMPs via confined polymerization of pyrrole in micropores. The conductive CMPs shows remarkably enhanced dielectric loss behaviors toward microwaves, and exhibits high electromagnetic absorption (EMA) performance, where the effective EMA bandwidth reaches 7.52 GHz and the maximal absorption achieves −59.7 dB. A confining model is adopted to explain the reason for the enhanced dielectric loss of conductive CMPs. This research expands application scope of CMPs in areas of conductive materials.
