چکیده

In the present work, hydroxypropyl cellulose and hematite (α-Fe 2 O 3 ) nanoparticles (HPC:Fe NPs) composites in various ratios (20:0.5, 20:1, 20:1.5, 20:2 wt:wt) were synthesised. X-ray diffraction (XRD), scanning electron microscopy (SEM), FTIR spectroscopy, thermal analysis (DSC, TGA) used to examine structural configuration properties of produced composites. The IR crystallinity indices (TCI, LOI, HBI) also computed. XRD patterns reveal a mixture amorphous HPC polymer components Fe NPs which identifies relationship between characteristics structure. Distributions dispersions on surface are apparent SEM. absorbance spectra that as quantity increased alterations intensity, area, band width found indicating change molecular HPC. Variations shape, size, shifts melting temperature higher temperatures by DSC TGA when amount is could be due interactions NPs. antibacterial activity nanocomposites was tested against Gram-positive Staphylococcus aureus Gram-negative Escherichia coli bacteria. have good activity, confirmed high potential activity. findings demonstrated HPC:Fe lead technological applications variety medical applications.
