Effect of Surface Treatment on the Morphology of Si3N4 Nanowires

Article Preview

Abstract:

The effect of surface treatment using polymer surface treating agent on the morphology of the Si3N4 nanowires was studied. The morphology, microstructure and surface chemical groups was characterized by using SEM, Granulometery, X-ray diffraction, Thermogravimetric analysis, diffuse reflectance infrared Fourier transform spectroscopy, The result s indicate that surface modify can not change the morphology of the nanowires. At the same time modifier on Si3N4 nanowire surface is chemical adsorption coating. Modifier coating occurred oxidative decomposition in 200-400oC
