| Abstract: | Chitosan films were prepared from dried prawn shell via chitin and then tensile properties like tensile strength (TS) and
elongation at break (Eb) of the films were evaluated. Six formulations were developed using methyl methacylate (MMA) monomer
and aliphatic urethane diacrylate oligomer (M-1200) in methanol along with photoinitator (Darocur-1664). Then the films were
soaked in the formulations and irradiated under UV radiation at different doses for the improvement of physico-mechanical
properties of chitosan films. The cured films were characterized by measuring TS, Eb, polymer loading (PL), water absorption
and gel content properties. The formulation containing 43% MMA and 15% oligomer in methanol solution showed the best performance
at 20th UV pass for 4 min soaking time. |
