CNT DECORATED CELLULOSE BASED FLEXIBLE NANOPAPER FOR TAILORMADE ELECTRICAL AND MECHANICAL PROPERTIES

Abstract

Nowadays, the preparation and development of sustainable functional nanomaterials which provides high performance is in trend. Miniaturization and portability found its way to achieve the peak order for most of the electronic products as well as degradable and flexible conductive material. In this study, synthesis of nanofibrillated cellulose based nanopaper accompanied the use of carbon-based fillers i.e., Multi walled carbon nanotube (MWCNT) is discussed. To achieve homogeneous MWCNT dispersion, it has been functionalized with the help of sulphuric and nitric acid. The nanopaper is prepared with the help of solvent casting method. By adjusting the concentration of Functionalized multi-walled carbon nanotubes (FCNTs), low-cost, thin, flexible and biodegradable FCNT/cellulose nanopaper have been created. This research looks at the effects of integrating functionalized carbon nanotubes into cellulose on the electrical, structural, mechanical and thermal characteristics of nanopaper. These nanopapers exhibit good thermal stability and high electrical conductivity. Therefore, these nanopapers can be considered as the opportunity to be an excellent electroconductive material for in electronic devices, energy storage or sensors.
