Abstract
Nano-sized zinc oxide (ZnO) particles and its composite were synthesised with xanthan gum (XG) and carboxymethyl cellulose (CMC) polymers.This work studied different concentrations of the surface adsorption of these polymers onto the Zinc oxide (ZnO) nanoparticles.The concentrations used as mass ratio were (1:1, 1:0.5 and 1:0.25w/w) for ZnO/polymer. The nanoparticles are then analysed using scanning electron microscopy (SEM), X-ray diffraction (XRD), atomic force microscopy (AFM), particle size and BET surface area.Composition of the samples was recognised with X-ray diffraction. The shape of particles changes with addition polymeric additives. It has been indicated that the low concentration polymers display a weaker effect on the surface of particles in comparison to the polymers with high concentration and CMC polymer better than XG polymer since it facilitated to produce finest nanoparticles with higher surface area.
