Abstract

The variation of microwave dielectric constant (εmw) and conductivity (σ) of doped polyaniline (PAN) materials as a function of polymer synthesis and processing, the resulting polymer crystallinity and local order, and the temperature of use is summarized. The shielding efficiency of intrinsically conducting PANs is estimated as a function of their intrinsic properties (εmw, σ), thickness, and source frequency. The high shielding efficiencies of highly conducting doped PANs are reported and compared to that of copper. The ease of tuning of intrinsic properties by chemical processing suggests the wide applications of PANs for shielding.
