【 摘 要 】

tsCarbon 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.
