Structural Features of Cellulose and Cellulose Nanocrystals via In Situ Incorporation of Magnetic Iron Oxide Nanoparticles: Modification and Characterization

This work reports on the structural modification of cellulosic materials with magnetic iron oxide nanoparticles through co-precipitation method. Cellulose is one most abundant natural polymers chemical variability brought about by presence several hydroxyl groups, allowing its surface modifications insertion groups to impact characteristics. Thus, objective this study was synthesize (MNPs) co-precipitation, followed in situ incorporation MNPs onto chemically purified cellulose (CPC) and nanocrystals (CNC). The composites were characterized for thermal properties using TGA, molecular structure FTIR, morphology SEM, elemental composition electron dispersion spectroscopy (EDS), crystallinity XRD. prepared presented improved crystal, thermal, properties. CNC-MNPs CPC-MNPs bore particle sizes 26.94 37.72 nm, respectively, whereas MNPs’ size 10.3 nm. EDS analysis indicated that Fe, C, Cl main elements present composites. Surface excellent sorption can be used industrial processes, such as wastewater purification, air filtration, various environmental remediation processes.
