dc.description.abstract | This comprehensive study investigates the properties of chemical nanomagnetic iron oxide
particles (CNMIOPs) synthesized through a chemical method. The primary objective is to examine
how pH levels and washing solvents affect the magnetism properties of these nanoparticles. Three
different pH levels (1.2, 7.5, and 12.5) using NaOH and two washing solvents (ethanol and water)
are employed. The characterization techniques include FTIR, SEM, TEM, XRD, ZSP, and VSM.
Furthermore, the study incorporates two specific pH- and solvent-dependent CNMIOPs into PCL
electrospun materials to analyze their performance in a targeted application. The results show that
pH and the washing process significantly affect the CNMIOPs’ properties. Higher pH levels result in
smaller particles with higher crystallinity and reduce crystalline anisotropy. SEM and TEM analysis
confirm different morphologies, including cubic, spherical, and elongated shapes. Ethanol-washed
CNMIOPs exhibit superior magnetic behavior, with the highest magnetization saturation at pH 12.5
(Ms = 58.3 emu/g). The stability of the CNMIOPs ranges from −14.7 to −23.8 mV, and higher pH
levels exhibit promising antioxidant activity. Furthermore, the study explores the effects of pH and
washing solvents on CNMIOP-infused nanofiber membranes, with better dispersion observed with
ethanol washing. Overall, this research provides valuable insights into the properties and behavior of
CNMIOPs under varying pH and washing conditions. | es |
