Storage Modulus (E’) and Loss Modulus (E’’) were plotted against frequency. The increase of frequency “freezes” the chain movements and a stiffer behavior was observed.OverviewDynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the behavior of . A sinusoidal stress is applied and the strain in the. .
Polymers composed of long molecular chains have unique viscoelastic properties, which combine the characteristics of and . The classical theory of elasticity describes the mechanical prop.
