Storage Modulus

Generally, storage modulus (E'') in DMA relates to Young''s modulus and represents how flimsy or stiff material is. It is also considered as the tendency of a material to store energy [ 244 ]. Loss modulus ( E'''' ) is regarded as the ability of a material to dissipate energy, which is sensitive to various transition, relaxation processes, molecular motions, morphology …
