Zinc oxide nanoparticles were successfully prepared with and without using surfactant. Poly Vinyl Alcohol (PVA)
was used as the surfactant and the prepared Nano powder was characterized using Scanning Electron Microscopy
(SEM) And X-Ray Diffraction (XRD). According to the characterization results it’s clear that the conventional
method of preparation i.e. without any surfactant highly affected by particle agglomeration and also the particle
separation is not good enough. But when prepared using a surfactant the particle agglomeration is very less and also
the particle separation is good. And the most important thing is that the particle size of zinc oxide prepared using
PVA is in the nanometre range whereas in conventional method of preparation particle size in the micron range.
According to the XRD characterization the average particle size of zinc oxide prepared using PVA as surfactant has
been determined using scherrer’s equation. The average particle size of zinc oxide nanoparticles has been found to
be 25nm
