1. A composite material with an electromagnetic interface (EMI) shielding material for frequencies of 1 MHz and greater and less than 1 THz, the composite material comprising:
a polymer matrix and a van der Waals material embedded in the polymer matrix, the van der Waals material forming quasi-one-dimensional atomic threads, and the van der Waals material being a trichalcogenide compound;
two-dimensional graphene embedded in the polymer matrix and mixed with the van der Waals material; and
wherein the polymer matrix includes an epoxy resin and the two-dimensional graphene embedded in the polymer matrix and mixed with the van der Waals material, and wherein the van der Waals material has a loading fraction of 1.0 vol. % to 50 vol. % of the composite material.
