In this experimental work, a procedure was introduced to redisperse WO3 nanoparticles in NMP. The primary nanoparticles were non-dispersible in NMP and the method includes dissolving the nanoparticles into an appropriate solution and adding ethylene glycol as dispersing agent. The optimum temperature and drying time to obtain a transparent and high stable colloidal dispersion were achieved. The final product powder redispersed in NMP and spin-coated on glass substrates. The surface of the layers was analyzed by scanning electron microscopy and ultraviolet–visible spectroscopy. The dynamic light scattering (DLS) technique was used to study the distribution, charge and zeta potential of the nanoparticles in the NMP matrix. Also, Energy-dispersive X-ray analysis (EDX) of the sample after dispersing and X-ray diffraction analysis (XRD) were taken. The results show a high stability of the final WO3 nanoparticles in NMP solution. [ABSTRACT FROM AUTHOR] |
