    • PURPOSE: A graphene fiber and a manufacturing method and usage of the same are provided to make a very light and flexible fiber than a metal wire, thereby providing excellent electric and thermal conductivity. CONSTITUTION: A graphene fiber manufacturing method is as follows. The graphene fiber forms a metal layer. The metal layer(120) comprises a plurality of linear patterns on a substrate. A graphene with the linear pattern is formed through an interaction by supplying reaction gas and heat. The reaction gas comprises a carbon source on the metal layer with the linear pattern. The substrate(100) is impregnated within an etching solution and selectively eliminates the metal layer of the linear pattern. The substrate separates the graphene(140) of the linear pattern and disperses a plurality of linear graphenes in the etching solution. A graphene fiber draws dispersed a plurality of linear graphenes to the outside of the etching solution.
    • 目的:提供石墨烯纤维及其制造方法和用途,以制造比金属丝更轻且柔软的纤维,从而提供优异的电导热性和导热性。 构成:石墨烯纤维的制造方法如下。 石墨烯纤维形成金属层。 金属层(120)在基板上包括多个线状图案。 通过提供反应气体和热量的相互作用形成具有线性图案的石墨烯。 反应气体包括具有线性图案的金属层上的碳源。 将衬底(100)浸渍在蚀刻溶液中并且选择性地消除线性图案的金属层。 衬底分离线性图案的石墨烯(140),并将多个线性石墨烯分散在蚀刻溶液中。 石墨烯纤维将多个线性石墨烯分散到蚀刻溶液的外部。
