Method for growing 2D/3D carbon-based nano- and submicron-sized structures

Abstract

A selective method for obtaining carbon-based two-dimensional and/or three-dimensional nano- or submicron-sized structures, including the following consecutive steps of selecting a suitable talc size, activating a surface of talc, thereby obtaining an activated surface; bringing the activated surface into contact with one or more polymers; and pyrolysis and/or carbonization of the polymers when in contact with the activated surface is provided. Depending on the aromaticity of polymers, growing 3D graphene structures may be initiated on the talc surface. The surface of the talc is activated with an activator selected from a list that includes carboxylic acids, metal salts and metal oxides. A hybrid additive which can be defined as talc provided with one or more carbon-based two and/or three-dimensional nano- or submicron-sized structures provided thereon is also provided.
