The growth of silver bromide nanoparticles on polyester fiber was achieved by sequential dipping steps in alternating bath of potassium bromide and silver nitrate under ultrasound irradiation. The effects of ultrasound irradiation, concentration and sequential dipping steps in growth of the AgBr nanoparticles have been studied. Particle sizes and morphology of nanoparticle are depending on power of ultrasound irradiation, sequential dipping steps and concentration. These systems depicted a decrease in the particles size accompanying an increase in the sonication power. Results suggest that an increasing of sequential dipping steps and concentration led to an increasing of particle size. The physicochemical properties of the nanoparticles were determined by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM).
通过在超声辐射下在溴化钾和硝酸银的交替浴中进行顺序浸渍步骤,在聚酯纤维上实现了银溴化物纳米颗粒的生长。研究了超声辐射、浓度和生长中顺序浸渍步骤对 AgBr 纳米颗粒生长的影响。纳米颗粒的粒径和形态取决于超声辐射的功率、顺序浸渍步骤和浓度。这些体系显示出随着超声功率的增加,粒径减小。结果表明,增加顺序浸渍步骤和浓度会导致粒径增大。通过粉末 X 射线衍射(XRD)和扫描电子显微镜(SEM)确定了纳米颗粒的物理化学性质。
