PPy
PPy is a significant conductive polymer with convenient preparation, tunable conductivity, chemical
stability, and resistance to corrosion [11,47] . Its high electrical conductivity makes it highly capable of absorbing
EMW. The conductivity may be adjusted by varying the permittivity through changes in the filler and
