Title:
MULTILAYER GRAPHITE SHEET WITH EXCELLENT ELECTROMAGNETIC SHIELDING CAPABILITY AND THERMAL CONDUCTIVITY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/212284
Kind Code:
A1
Abstract:
An embodiment relates to a multilayer graphite sheet with excellent electromagnetic shielding capability and thermal conductivity, and a manufacturing method therefor, wherein the multilayer graphite sheet has a multilayer structure of five or more layers in total and can be manufactured to have a thick thickness of 70 μm or more such that the electromagnetic shielding capability can be significantly improved. In addition, the multilayer graphite sheet is manufactured by graphitizing a hybrid laminate in which heterogeneous materials are mixed such that thermal conductivity and electromagnetic shielding capability can be simultaneously realized at a lower cost, thereby being useful as a thick film sheet which used in various applications such as home appliances and electric vehicles.
