INTRODUCTION OF AN AROMATIC COMPOUND ONTO A NANOCELLULOSE SURFACE AND ITS FABRICATION METHOD OF AN ORGANIC-INORGANIC COMPOSITE

摘要

The present invention relates to a method for producing a nanocellulose / graphene-based composite sheet and its use. The present invention provides a method of making a nanocellulose / graphene organic-inorganic composite sheet comprising the steps of: (a) surface-modifying a nanocellulose material with an aromatic compound; (b) preparing a sheet of said surface-modified nanocellulose material; And (c) coating the prepared sheet with a graphene solution to prepare a nanocellulose / graphene-based composite sheet. The method of the present invention comprises the steps of preparing a nanocellulose sheet having excellent dispersibility through surface-modification and uniformly dispersing graphene on the nanocellulose sheet through the interaction between the aromatic hydrocarbon and graphene in the surface-modified nanocellulose Based nanocellulose / graphene-based composite sheet. Accordingly, the nanocellulose / graphene inorganic composite sheet of the present invention can be easily and effectively applied to wood products, films, porous materials, supercapacitors, substrates and bionanocomposites.
