Event Abstract Back to Event Characterization of cellulose nanowhiskers by dynamic light scattering and atomic force microscopy Tolou Shokuhfar1 1 University of Illinois at Chicago, Bioengineering, United States In current study, the effect of centrifugation and sonication on the size distribution of Cellulose nanowhiskers (CNWs) was studied using dynamic light scattering and their morphological properties were investigated using atomic force microscopy. CNWs were prepared by sulfuric acid hydrolysis of cotton balls, microcrystalline cellulose and filter paper. We show that centrifugation can be used for successful fractionation of CNWs. In addition, sonication, which is usually used as the final step for the even distribution of CNWs in water, affects the size of CNWs. We have shown that the size of CNWs stays stable in water, the sonication energy affects the size of CNWs, and that ultracentrifugation is a useful technique for obtaining monodispersed CNWs and eliminating micro sized impurities.
