Tailoring Nanocellulose Properties through Surface Modification:An Elemental Analysis Approach

Due to their high surface energy compared to polymers, Nanoparticles exhibit a strong tendency toaggregate when dispersed within a polymeric matrix. This phenomenon arises from a lack offavorable interactions with the polymer chains, hindering their uniform distribution throughout thesubstrate. Surface modification of nanoparticles through introducing functional groups, such as silanecoupling agents, proves to be a successful strategy for overcoming this challenge. Thesemodifications achieve a twofold effect: they create steric hindrance, disrupt existing agglomerates,and simultaneously enhance the compatibility between the nanoparticles and the polymer chains. Thisimproved compatibility promotes a more homogeneous dispersion and contributes to a more stablemorphology within the nanocomposite, enhancing mechanical properties. This research investigatesthe surface modification of cellulose nanoparticles, employing elemental analysis to evaluate theeffectiveness of the modification process in promoting desired polymeric interactions.
