tests. Dynamic mechanical analysis (DMA) methods are particularly useful and are being largely used to investigate fiber/matrix adhesion [ 4 ], as well as the structure and the viscoelastic behavior of polymers and polymer composites [ 5 , 6

calorimetric (DSC), and dynamic mechanical analysis (DMA). Thermal analysis provided information on thermal stabilities and thermal transition of the Cs/ODAC bio-composite films and offered an alternative approach to study the structure of the polymer network
