Title: Graphene and Carbon Nano Tube Industrialization via nanotechnology in energy storage coating
Abstract:
In this century, the importance of graphene and CNT in industrial applications cannot be overstated. To achieve deep decarbonization and avoid exceeding the 1.5°C climate target, we may need to remove 100 to 1,000 gigatonnes of CO2. Carbon Nanomaterials and nanotechnology are playing a key role in this. Graphene and CNT, with their unique properties, have found applications in numerous industrial sectors. Their impermeable and conductive nature can replace currently used anticorrosive toxic pigments in coating systems, and graphene can be a crucial component as a next-generation additive for many industrial applications. The current challenges lie in the availability of cost-effective, high-quality materials and their effective incorporation into the product matrices using nanotechnology.
On overcoming these factors, graphene may attract significant demands regarding volume consumption. Graphene can be produced on industrial scales and cost-effective top-down routes such as high-pressure mechanical, chemical, and electrochemical exfoliation (2). Depending on end applications, graphene can be chemically tuned and modified via functionalization to easily incorporate into product matrices. This talk discusses different Carbon nanomaterials industrialization routes and their impact on the quality of graphene produced in terms of energy input. A few methods made graphene with an average thickness below five layers with the lowest defects. However, the mechanical exfoliation route produced a higher yield of graphene with a lower number of layers. Graphene plays a key role in Energy storage applications and hydrogen transportation. The talk will address the commercial development of industrial energy storage applications to continue to lead the Li Battery high energy density applications.
