Mechanical and Chemical effect of Chitosan on BisGMA/PEOZ Blend Based Composites

Ankita Pritam Praharaj | Dibakar Behera

Abstract: This paper describes the mechanical and chemical effect of chitosan as reinforcing filler (0; 10; 20; 30; 40; 50 wt %) on Bisphenol-A glycidyldimethacrylate (BisGMA) -Polyethyleneoxazoline (PEOZ) blend based composites. For this; BisGMA was synthesized followed by the preparation of various BisGMA/PEOZ blends using varying proportions of PEOZ (0; 30; 50; 60; 70 wt %). Mechanical properties of blends like tensile stress; Youngs Modulus; elongation at break and impact strength were studied. The results suggested that the blend having 50 wt % of PEOZ and BisGMA is the optimum composition due to maximum improvement in all the mechanical properties. Thus; the composites were fabricated using the 50 wt % blend composition alongwith different weight percentage of chitosan and their properties were studied. The tensile strength; Youngs Modulus; impact strength and hardness of composites were found to be increasing with increase in chitosan loading; reached an optimum at 40 wt % and thereafter decreased with further increase in chitosan content; whereas elongation at break decreased with chitosan content. Chemical resistance and ageing studies of composite systems were also investigated to ascertain their structural applications in aerospace and automobile industries.
