Thermal degradation study of cotton waste pulp-based cellulose nanocrystals

Abstract

Researchers are interested in cellulose nanoparticles because they are eco-friendly biomaterials with a wide range of industrial and residential applications. The purpose of this investigation is to identify the thermal degradation parameters of the isolated crystalline cellulose nanoparticles from high-quality cotton pulp in order to identify their potential as heat transfer media in large-scale heat exchange applications. A thermal parametric investigation of the nano particle sample was carried out using a variety of methods, including X-Ray Diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FTIR), Thermo gravimetric analysis (TGA), and Differential Scanning Calorimetry (DSC). The isolated nanoparticles have the shape of cellulose nanocrystals (CNC). An FCC lattice structure with a maximum crystallinity index of about 52% was discovered by XRD investigation. The maximum temperature of thermal deterioration was indicated by TGA data to be around 361 °C. The nano particle sample's thermal degradation temperatures and specific heat values were detailed by DSC analysis.
