Abstract

Nafion thin films (<2μm) were fabricated using the spin coating technique. The effects of varying the Nafion concentration (5%, 10%, and 15%) and spin coating angular velocity (1500rpm, 2000rpm, and 2500rpm) on the thickness and morphology of the films were investigated. The deposition of the films onto the substrates was verified using energy dispersive x-ray (EDX) and the surface morphology was characterized by scanning electron microscopy (SEM). Surface morphological results show that the films followed the contour of the substrate onto which they are deposited and nanometer scratch-like features appear at high magnification (x35000). Thickness measurements were graphed against the different parameters and results show that thickness of Nafion films
decrease with increasing angular velocity and increase with increasing concentration.
