Plasma treatment for enhancing mechanical properties of biodegradable PVA/starch blends

Non-chemical modification of PVA/starch blend was investigated using Electrical Discharge Plasma (EDP) treatment. Two series of biodegradable Polyvinyl alcohol (PVA)/starch blends, i,e, PVA with/ without plasma treatment (B/P) ,also varied concentration solutions were produced . Fourier Transform Infrared (FT-IR) spectroscopy and Tensile Strength (TS) revealed structural and chemical changes in the modified materials.
