Development of High-performance Naonocellulose from Natural Sources

Authors: Xu, Hui; Khosrozade, Ali; Zhong, Wen
Description: The increasing environment awareness has been a great push for the development of sustainable, eco-friendly, and biodegradable materials from natural sources that can replace non-renewable materials. Abundant natural plants and annual crops grown in Canada are ideal sources for cellulose nanofibers. These are advanced biomaterials with low density, high mechanical strength and ultrahigh surface-to-volume / mass ratios, which contribute to their exceptional performance in absorption/adsorption, filtration and incorporation of bioactive molecules. Their potential applications include wound dressings, drug delivery, scaffolds for tissue engineering, water purification and supercapacitors.

This study is to isolate high-performance nanocellulose from hemp fibers using a simple and environmental friendly approach. Alkali pre-treatment will be used to further remove lignin and hemicellulose from the hemp fibers. Cellulose nanofibers will be mechanically disintegrated through high speed blending. The morphology of the cellulose nanofibers will be examined by Atomic Force Microscope (AFM) and Scanning Electron Microscope (SEM). Cellulose nanofiber membranes and cellulose hydrogels composed of crosslinked carboxymethylated cellulose will be prepared and characterized for their applications in a variety of areas. The results of the study are expected to lead to the development of high-performance cellulose nanofibers and their hydrogels for high-value added applications using a simple method that is scalable for industrial manufacturing.
