Abstract :

Polymer films of Polymethylmethacrylate at 0.5, 1 and 2N concentrations and its composite with Fe2 O3  at different weight percent have been used for measurement of Mechanical properties such as stress, strain, and Young’s modulus at an ambient temperature. The value of stress is decreased as concentration of the film of Polymethylmethacrylate increased. In case of its composite the value of stress is increased as the weight percentage of Fe2 O3 increased. The young’s modulus decreased and the strain at eak increased as concentration of PMMA film increased. In case of its composites the young’s modulus as well as the strain at eak both are decreased as weight percentage of Fe2 O3   increased. Further, the films of polymer and its composites are irradiated by an electron beam at a dose rate of 100 kGy. The weight loss and melting temperatures for these samples before and after electron irradiation are measured using TGA and DSC. The weight loss of PMMA after electron irradiation is higher than that of its pristine, whereas in case of composite film the weight loss after electron irradiation is lower compared to that of its pristine values. In DSC measurements it is observed that melting temperature is occurred at 394.640 C for polymer of PMMA and at 392.850 C for its composite. This leads that addition of Fe2 O3 reduced melting temperature of the PMMA by 1.79 0 C. The melting temperature after an electron irradiation is occurred at 388.160 C for PMMA and at 384.74 0 C for its composite. Hence these observations are indicated in lowering of their melting temperatures as compared to that of their pristine measured values.
