This article reports the modified surface morphology of Poly-vinyl Alcohol (PVA) films using electro-spraying coating technique. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) were conducted to examine the surface structure of the prepared PVA films. Intriguingly, the novel micro-level developed surface, twisted by electro-spraying is very promising for humidity sensors. The...
A novel structured of nanoporous vanadyl 2,11,20,29-Tetra Tert-Butyl 2,3 Naphthalocyanine (VTTBNc) films were prepared by template-assisted method. The structure and morphology of the fabricated VTTBNc nanostructures were studied by field emission scanning electron microscopy (FESEM) and micro-Raman spectroscopy. The VTTBNc nano-porous films showed a potential application in humidity sensors.
