Highlights

  • Carbon nanotubes/polymerizable ionic liquid copolymer (CNTs/PIL) provides nucleation sites and inhibits the combination of microcellular structures.

  • The increase in evaporate time improves the conductive network of composite foams.

  • Electromagnetic interference shielding effectiveness (EMI SE) and specific EMI SE of the composite foam displays 69.9 dB and 211.5 dB/(g cm−3).

  • Polarization, conduction and magnetic loss attenuate microwave energy.
