ELCTRICALLY CONDUCTIVE HYBRID MEMBRANE MAKING METHOD THEREOF SECONDARY BATTERY AND ELECTRONIC DEVICE COMPRISING THE SAME

The present invention is to provide an electrically conductive composite membrane excellent in processability, flexibility, and barrier properties. Provided are an electrically conductive composite membrane, a method of manufacturing the same, and a secondary battery and an electronic device including the same. According to the present invention, the electrically conductive composite membrane comprises: a solid film substrate including a curable material; and electrically conductive particles disposed on the solid film substrate. The elastic modulus of the solid film substrate is 10 MPa to 1000 MPa, and the electrically conductive particles are each exposed on both sides of the solid substrate. 전기 전도성 복합막, 그 제조 방법, 이를 포함하는 이차전지와 전자기기가 제공된다. 전자 전도성 복합막은 경화성 재료를 포함하는 고체 막 기재, 및 고체 막 기재에 배치되어 있는 전기 전도성 입자를 포함하되, 고체 막 기재의 탄성률은 10 MPa 내지 1000 MPa 이고, 전기 전도성 입자는 고체 막 기재의 양 면으로 각각 노출되어 있다.
