The storage modulus is a measure of how much energy must be put into the sample in order to distort it. The difference between the loading and unloading curves is called the loss modulus, E ". It measures energy lost during that cycling strain. Why would energy be lost in this experiment? In a polymer, it has to do chiefly with chain flow.
Elastic storage modulus (E′) is the ratio of the elastic stress to strain, which indicates the ability of a material to store energy elastically.

When the storage modulus is high, the more difficult it is to break down the polymer, which makes it more difficult to force through a nozzle extruder. Therefore, the nozzle can become clogged and the polymer cannot pass through the opening. However, the polymer with the highest storage modulus will also be the most stable after printing.
It is also considered as the tendency of a material to store energy . 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 and other structural heterogeneities.
