The storage modulus of a polymer in the rubbery plateau region was used to determine the cross-link density. The cross-link density (Table 12.5) of the 40% styrene film sample at approximately 40 °C was 66.7 mol/m 3. The cross-link density of the 60% MMA film sample at approximately 50 °C was 77.1 mol/m 3. Figure 12.23.

The measured tensile strength of the polymer film was 31 MPa with a Young''s modulus of 1.26 GPa, whereas the average storage modulus exceeded 960 MPa. The failure strain of the material was 4.4%. It was found that the film is thermally stable at low temperatures, down to −150 °C, and decomposition of the material occurs at 350 °C.

A state-of-the-art review of the fabrication and characteristics of titanium

Rheological Analysis of Dispersions by Frequency Sweep Testing

A frequency sweep is a particularly useful test as it enables the viscoelastic properties of a sample to be determined as a function of timescale. Several parameters can be obtained, such as the Storage (Elastic) Modulus (G''), the Viscous (Loss) Modulus (G"), and the Complex Viscosity (η*). The storage modulus can be used as a measure of the
