Title:
FLEXIBLE ELECTROMAGNETIC WAVE SHIELDING MATERIAL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/110969
Kind Code:
A1
Abstract:
A flexible electromagnetic wave shielding material is provided. The electromagnetic wave shielding material according to one embodiment of the present invention comprises: a conductive nanofiber web having a nanofiber web formed of nanofibers and including a plurality of pores and a metal layer covering a part of the nanofibers disposed on a surface portion of the nanofiber web, in which metal particles are provided on at least a part of the pores; and an elastic member bonded to one surface of the metal layer of the conductive nanofiber web. Due to these features, as the electromagnetic wave shielding material has excellent elasticity, it is possible to freely modify the shape thereof as desired and to attach the electromagnetic wave shielding material to be completely adhered to a surface even if the surface where it is disposed has a curved shape such as uneven or stepped surfaces, and thus it is possible to exhibit excellent electromagnetic wave shielding performance. Further, degradation of the electromagnetic wave shielding performance can be prevented even with various shape changes. Furthermore, even when components are mounted with a high density in a narrow area, the electromagnetic wave shielding material can be provided to completely adhere to the mounted components by overcoming tight spacing and steps between the components, such that the electromagnetic wave shielding material can be easily adopted in compact or flexible electronic devices.
