Determination of Electrical Conductivity of Aluminum Nano Films prepared by Flame Thermal Spray

Abstract

This study measured the electrical conductivity of the Al coating layer deposited on acrylonitrile butadiene styrene (ABS) by flame thermal spraying. The results showed that the electrical conductivity of aluminum coating on the ABS polymer substrate were good but lower than that in bulk aluminum, with values of 1.68×10⁴ – 2.17×10⁴ Ώ^-1.cm^-1. The scanning electron microscopy (SEM) also showed good adhesion force between the Al coating layer and the surface of the polymeric substrate; the results of the x-ray diffraction (XRD) showed no oxidation. The contact angle for the ABS substrate was 36.442°, meaning that the ABS surface is hydrophilic and has good surface energy and adhesiveness.
