Abstract: | The growth of magnesium hydroxide nanostructures on silk yarn was achieved by sequential dipping steps in alternating bath of magnesium nitrate and potassium hydroxide under ultrasound irradiation. The effects of ultrasound irradiation, concentration, pH and sequential dipping steps on growth of the Mg(OH)2 nanostructures have been studied. Morphology of the nanostructures, depending on pH and with decreasing pH from 13 to 8, changed from nanoparticle to nanoneedle. Results show a decrease in the particles size as the concentration and sequential dipping steps increased. The physicochemical properties of the nanostructures were determined by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and wavelength dispersive X-ray (WDX). |
