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 shielding guest material. The specific makeup of the shielding material and fabrication procedure of the shielding material is also included herein.
Claims30
An electromagnetic interference (EMI) shielding material comprising:
- a biopolymer or polymer, dissolved in organic solvents, and shielding guest materials;
- the shielding guest materials comprising at least one of particles, powders, tubes or rods, flakes, fiber or sheets;
- wherein the shielding guest material is functionalized by surface modification;
- surface modification comprising conjugation of chemicals or biomolecules onto a surface of the shielding guest material.
