Synthesis and characteristics of gold nanoparticles/Epoxy polymer Nano composite material

Gold nanoparticles were prepared by Turkevich method. These nanoparticles were capped with type of Epoxy polymer. Gold nanoparticles were characterized using UV-visible absorption spectrophotometer to determine the location and the intensity of the SPR absorption package of the uncapped gold Nano composite and those capped with the drugs. It was found that the SPR of the uncapped nanoparticle with Epoxy polymer was at (526 nm), while when capped with the Epoxy polymer was at (670 nm). Characterizing of the shape and size of pure Gold nanoparticles and that capped with Epoxy polymer were done using transmission electron microscopy (TEM).It was found that the uncapped Nano composite spherical shape and diameter range between (5-15)nm and these nanoparticles form the micrographs of transmission electron microscopy) showed that Nanocomposit Epoxy polymer has a fluffy aggregation and the form of Nano composite Epoxy polymer as a flakes or Nano-sheets and Particles Size diameter range between (10-20)nm. Gold nanoparticles were characterized using Atomic force microscopy (AFM), For the purpose of determining the gold nanoparticles structure, X-ray diffraction was used
