Flexible electromagnetic wave shielding material, electromagnetic wave shielding type circuit module comprising same and electronic device furnished with same

Abstract

Provided is a flexible electromagnetic wave shielding material. An electromagnetic wave shielding material according to an embodiment of the present invention is implemented to include a conductive fiber web including a conductive composite fiber including a metal shell part covering an outside of a fiber part such that the conductive composite fiber forms multiple pores; and a first conductive component provided in at least some of the pores. The electromagnetic wave shielding material is so excellent in flexibility, elasticity, and creasing/recovery that the electromagnetic wave shielding material may be freely changed in shape, and can be brought in complete contact with a surface where the electromagnetic wave shielding material is intended to be disposed even if the surface has a curved shape such as an uneven portion or a stepped portion, thus exhibiting excellent electromagnetic wave shielding performance. Also, it is possible to prevent deterioration of the electromagnetic wave shielding performance even with various shape changes. Furthermore, even if parts are provided in a narrow area at a high density, the electromagnetic wave shielding material can be brought into complete contact with the mounted parts by overcoming a tight space between the parts and a stepped portion. Thus, the present invention can be easily employed for a light, thin, short, and small or flexible electronic device.
