Assuming that the OCA is thermorheologically simple, the storage modulus curves can be obtained by converting frequency coordinates to time coordinates at different temperatures. The DMA dynamic experiment results at different temperatures are as shown in Figure 11, where the storage modulus presents a decreasing trend over time.

The shrinkage stress is a function of the cured shear storage modulus of the (L)OCA, the volumetric shrinkage, and the stress relaxation. If the material is able to exhibit sufficient stress relaxation, it may be able to dissipate a majority of the shrinkage stress from cure and minimize the impact on mura.

Dynamic modulus

The ratio of the loss modulus to storage modulus in a viscoelastic material is defined as the, (cf. loss tangent), which provides a measure of damping in the material. tan ⁡ δ {displaystyle tan delta } can also be visualized as the tangent of the phase angle ( δ {displaystyle delta } ) between the storage and loss modulus.

Tan delta is the ratio of loss modulus to storage modulus and is a means of determining the ability of a material to dissipate energy (Sorbothane 2015). A master curve of the material can be used to determine, evaluate, and compare different (L)OCA materials (Pocius 2002 ).

4.8: Storage and Loss Modulus

The slope of the loading curve, analogous to Young''s modulus in a tensile testing experiment, is called the storage modulus, E ''. 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 ".
