Whilst, the XRD study confirmed the crystal structure of CNC is obeyed cellulose type I with crystallinity index ∼90%. Malvern Zetasizer Nano-ZS ZEN 3600 Software: Zetasizer Software Version 7.13 Capabilities: Measurement Molecular size Molecular weight Particle size range of 0.3 nm to 10 m Zeta potential Temperature range of 0° C to 90° C. The Zetasizer Nano ZS is the pinnacle of the Malvern Zetasizer Nano series and can measure all three parameters with no performance compromises. Based on the results obtained, the combination of sonication and chemical treatment was great effective in extraction of CNC with the average dimensions (diameter × length) of 35.2 ± 7.4 nm × 238.7 ± 81.2 nm as confirmed from TEM. These characteristics were monitored using TEM, SEM, AFM, XRD and FTIR spectra for following the changes in functionality. A thorough investigation pertaining to nanostructural characteristics of CNC was performed. The latter was freeze-dried to produce CNC powder. Acid hydrolysis mechanism exactly referred that, the amorphous regions along with thinner as well as shorter crystallites spreaded throughout the cellulose structure are digested by the acid leaving CNC suspension. The CNC yield attained values of 15% from purified sawdust. After complete reaction, CNC were collected by centrifugation followed by dialyzing against water and finally dried via using lyophilization technique. Thus, sawdust after being alkali delignified prior sodium chlorite bleaching, was subjected to sulfuric acid with concentration of 65% (w/w) at 60 ☌ for 60 min. Isolation of CNC from sawdust was conducted as per acid hydrolysis which induced by ultrasonication technique. Herein, we investigate the potential of commercially non-recyclable wood waste, in particular, sawdust as a new resource for CNC. Owing to their mechanical, optical, chemical, and rheological properties, CNC gained significant interest. Cellulose nanocrystal (CNC) is a unique material obtained from naturally occurring cellulose fibers.
