The surface modification by cold argon plasma jet on the biodegradable films from Perna Viridis shell

Abstract

The present study aims to characterizing the properties of chitosan film (biodegradable films) with prepared from the Perna Viridis Shell, and investigate the effect of an atmospheric pressure plasma jets (APPJs) in pure argon used to modify the surface of chitosan film. The properties have also been discussed in detail with X-Ray Diffraction (XRD), Energy Dispersive X-rays spectrometer (EDXRF) and scanning electron microscope (SEM). The XRD and SEM were explaining the crystalline and morphology properties, while the chemical composition in the chitosan film used EDXRF. The result of the XRD pattern indicated the chitosan film, can be observed the mixture phase between chitosan hydriodide phase and calcium acetate hydrate. After that, the surface modification by the APPJs exhibit the water contact angle decreased as the duration of the plasma treatment. Another that, the SEM micrograph exhibited a significant different in surface topography of the film after plasma treatment and increased the chitosan film have surface roughness.
