【Abstract】 A method,homogeneous reaction and interface growth,has been used to fabricate nano-materials.Copper nanoparticles with different morphologies have been prepared by liquid-liquid interface growth in the presence of Polyvinylpyrrolidone and the mechanism of interface growth has been discussed in this paper.The effect factors,such as interface growth and reaction temperature,have been investigated.The products have been characterized with transmission electron microscopy(TEM),scanning electron microscopy(SEM),X-ray diffraction(XRD),and ultra-violet-visible(UV-Vis).更多还原
