Preparation CuO and CuCO3Cu (OH) 2 Crystal Nano Particles by Using Microemulsion Method

Abstract

A microemulsion method for preparing colloidal copper nanoparticles inmicroemulsion is reported. The obtained copper carbonate CuCO3⋅Cu(OH)2 nanoparticleand copper oxide CuO nanoparticle were characterized by powder X-ray diffraction(XRD), atomic force microscopy(AFM),transmission electron microscopy (TEM) and Xrayfluorescent(XRF) analysis, the purity of material and average particle size about 10nanometer.. A microemulsion is thermodynamically stable ,optically isotropic derisionof two immiscible liquids consisting of nano-size (CuSO4.5H2O) domains of one orboth liquids in the other (white oil),stabilized by an interfacial film of the surface-activemolecules. The materials mixed to have new immiscible solution , add chemical materialsto reduce surface tension and to reduced interfacial atomic bonds to very low level , thevery fine dispersed spherical micelles in microemulsion are thermodynamically stabledue to a combination of very low interfacial tension very small nanoparticles diameter of(2-5) nm. Addition another of chemical material as react agent or reduced agent andprecipitate agent to product final material CuCO3⋅Cu(OH)2.Synthesis of monodispersedCuCO3⋅Cu(OH)2 nanoparticles with refractive index similar to glass plates by usingultrasonic spray pyrolysis technique by method .Yielding homogeneous ,low defect thinfilms of high transparency ,that can be used as color filters for liquid crystal displays .
