Title:
GRAPHENE-BASED COMPOSITE, PROCESS FOR PRODUCING SAME, AND ELECTRONIC DEVICE OBTAINED USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/105768
Kind Code:
A1
Abstract:
The present invention relates to a composite which includes both a layer comprising a polymer and a single or multiple graphene sheets, part or the whole of the graphene having been perpendicularly or obliquely arranged on the layer comprising a polymer. The composite has a wider surface area due to the three-dimensional arrangement of the graphene and thereby exhibits improved electrochemical performance and excellent stability. Thus, the composite can be utilized in various electronic devices including electrodes, sensors, batteries, and displays.
