Isolation of nanocellulose from Dodonaea viscosa plant: structural and thermal properties.

In this research work, cellulose was isolated from Dodonaea viscosa plant by means of various chemical processes followed by the preparation of nanocellulose through sulfuric acid hydrolysis. These chemical processes begin with the removal of non-cellulosic material such as lignin, pectin, crude wax, and hemicellulose followed by alkaline treatment and chlorine-free bleaching methods. Fourier transform infrared (FTIR) spectroscopy showed the successful isolation of cellulosic material after removing hemicellulose, lignin, and other extractives. Thermogravimetric analysis (TGA) elucidated the thermal degradation profile of the cellulose-based materials obtained after various chemical procedures at each step. Additionally, nanocellulose was prepared from cellulosic material using acid hydrolysis, and its structural and thermal properties were discussed. Nanocellulose extraction from the lignocellulosic biomass sources and its further utilization has been the subject of intensive research as the global community needs the use of green chemistry principles in recent life. Nanocellulosic material due to its unique characteristics and properties is of great importance and has many applications in various industries, including materials science and engineering.
