Abstract
With the massive use of cotton fibers in textile industries, the wastes produced have continuously increased, causing environmental problems. Valorization of these viable and sustainable cellulose sources may offer a variety of value-added products. Cellulose nanocrystals (CNCs) have gained attention as they are renewable, inexpensive, biocompatible materials with excellent properties that allow them to be used in many applications. In this study, CNCs were isolated from cotton linters by sulfuric acid hydrolysis, characterized by FTIR analysis for functional groups identification. XRD revealed a crystallinity value of 63.2 % with an identical peaks pattern to CNCs. TEM analysis illustrated rod-shaped structures in the nanorange. The degradation temperature for the CNCs was 170 oC based on TGA analysis.
