Abstract
An electromagnetic interference (EMI) shielded device which includes an object to be shielded and an EMI shielding material encompassing the object. The EMI shielding material is made up of, but not limited to a broadband biopolymer or polymer dissolved in organic solvents, and metal and carbon-based nano-powders or nanoparticles. The specific makeup of the shielding material and fabrication procedure of the shielding material is also included herein.
