Synthesis and characterization of lead oxides for preparation of nanocomposites with polyamide

Lead oxide nanoparticles with diameters between 100 to 250 nm were obtained using a polymeric precursor method in the presence of citric acid and ethylene glycol. X-ray diffraction (XRD) and dynamic light scattering to measure the size and zeta potential in solution in dispersions with different pH were used to characterize the as-obtained samples. The nanoparticles were incorporated into polyamide 6.6 and composite films were prepared by electrospinning being evaluated the variation of the mechanical properties of the polymer and its effectiveness in attenuation of X-rays.
