Abstract
The present invention relates to a graphene composition having liquid crystalline properties and a preparation method thereof, and more particularly to a graphene composition wherein graphene having useful electrical properties is uniformly dispersed in a medium, whereby it is chemically and physically stable, exhibits a liquid crystal phase in a wide temperature range and has good compatibility with other compounds, and to a preparation method thereof. In the graphene composition, liquid crystalline properties are imparted to graphene, which can be produced in large amounts and has excellent mechanical, chemical and electrical properties, and thus the graphene composition can provide a chance to apply functional carbon materials in various fields, including nanocomposites, energy storage materials, and photonics.
