Executive Summary : | The modification of the properties of solid supports by immobilizing guest material on solid supports results in an interesting approach for the manipulation of the properties of solid supports [1, 2]. This type of chemistry is one of the defining concepts of supramolecular (host-guest) chemistry, which describes the formation of unique structural complexes by interaction [2-4]. These interactions will be much more interesting if we use solid support like 2D materials and guests like ionic liquids (IL) [5-7] with the application of an electric field. The diverse structural topologies of 2D materials with high crystallinity have the potential to capture molecular guests of different sizes and shapes [8-15]. On the other hand, ILs is low melting point salts having a massive range of cations and anions. Therefore, a variety of surface interactions may be responsible for modifications in host networks or solid support as well as in the guest [4-6, 16, 17]. Also, the application of variable electric fields to IL-impregnated 2D materials could change the dielectric disorder in 2D materials. It is expected that the fluctuating dielectric surrounding 2D materials will induce a large variation in band gap and binding energies. Optimized IL impregnated 2D materials with controlled electric fields would be a good probe to tune the structural, optical, and electronic properties of 2D materials [18-22]. However, no studies are available on modification in 2D materials via IL immobilization and electric field. The modified 2D materials and IL impregnated 2D materials would be potentially useful as new material combinations for electronics, extraction, adsorption energy storage etc. To leverage the advantages of 2D materials, ILs and electric field, I will monitor the dielectric disorder in 2D materials, which will be induced by IL in the presence of an electric field. In this project, I propose a novel approach to introducing IL on solid support of 2D materials, followed by the application of an electric field to modify the structural, electronic, and optical properties of the 2D materials. Additionally, the incorporation of ILs into 2D and layered materials may exhibit fast kinetics of ionic conduction. This is important in the pursuit of developing energy storage with high power and high energy densities while preserving high volumetric capacity. Therefore, it would be interesting to understand the properties of solid supports when modified with ILs under the exposure of a variable electric field. Studies in these directions will definitely help to improve the understanding and application of modified materials using IL and electric fields. |
