Synthesis and Characterization of Silane Modified Iron (iii) Oxide Nanoparticles Reinforced Chitosan Nanocomposites

Silane modified iron (III) oxide (SiFe2O3) nanoparticles reinforced chitosan (CS) nanocomposite membranes were prepared by solcast transformation method. The iron (III) oxide nanoparticles and nanocomposite membranes were investigated by UV (Visible) spectroscopy, FT-IR spectroscopy, XRD, SEM and TEM. The size and shape of iron (III) oxide and Si-Fe2O3 nanoparticles were determined by XRD and TEM. The Si-Fe2O3 nanoparticles were reinforced homogeneously within the chitosan matrix which could be assigned due to the hydrogen bonding between CS and Si-Fe2O3. The mechanical properties of nanocomposites were investigated. The results showed that the tensile and elongation properties of the Si-Fe2O3 nanoparticles reinforced chiotsan nanocomposite increases upto 6 wt.% and then declines.
