Abstract
An electromagnetic wave-absorbing web for controlling interference by electromagnetic wave at a low frequency band generated from various electric and electronic parts and for securing strength without added material and achieving lightweight is provided. The web is manufactured of a mixture solution in the form of a fabric having a mesh structure, wherein the mixture solution is made by mixing a conductive nanomaterial, a magnetic nanofiller, a binder, and a solvent.
Claims12
A web for absorbing an electromagnetic wave manufactured of a mixture solution in the form of a fabric having a mesh structure,
- wherein the mixture solution is a mixture of a conductive nanomaterial, a magnetic nanofiller, a binder, and a solvent,
- wherein the magnetic nanofiller comprises a magnetic metal having a magnetic permeability different from that of the conductive nanomaterial, and
- wherein the magnetic metal is in the form of nanowire or particles and filled in gaps of the conductive nanomaterial, and wherein the web has a yarn-shape and the mesh structure is formed within the yarn-shaped web.
