Abstract:
An electromagnetic wave shielding material and a sheet using the same are described. Also described is a gel state electromagnetic wave shielding material including an ionic liquid, and fine particles capable of reflecting, suppressing or absorbing an electromagnetic wave suspended in the ionic liquid. The electromagnetic wave shielding material may provide both high electromagnetic interference shielding ability and flexibility when used in sheet form, and in some applications, may provide flame and heat resistance.
