Influence of argon irradiations on modifying the surface properties and optical behavior of polymer composite films‏

The composites PVA/CuO, which is made of copper oxide nanoparticles (CuONP) and polyvinyl alcohol (PVA) are created by the solution casting production process. The surface properties of the PVA/CuO composite were then altered using a cold cathode ion source for using these samples in optical devices. The PVA/CuO samples were exposed to argon fluencies of 3 × 1017, 6 × 1017, and 9 × 1017 ions.cm−2. By raising the fluence from 3 × 1017 to 9 × 1017 ions.cm−2, the contact angle is reduced from to 48.43° to 32.52°, while the work of adhesion increased from 119.93 mJ/m to a 132.86 mJ/m
