Characterizations
The dynamic mechanical properties of the obtained membrane were performed using Dynamic Mechanical Thermal Analyser (DMTA; Model-V, supplied dy Rheometric Scientific) The dynamic mechanical properties of the obtained membrane were performed using Dynamic Mechanical Thermal Analyser (DMTA; Model-V, supplied dy Rheometric Scientific). Tte shape of test sample was rectangular,25 mm long, 10 mm wide and 1.5 mm thick. the single cantilever mode of deformation was used under the test temperature range from-90oc to 90oc with a heating rate of 3oC/mm. the test frequency being 1 Hz. The cooling process was achieved through liquid nitrogen.
