The storage modulus exhibits the expected softening with increased temperature 21 while the loss tangent has a peak at around 90°C associated with the material''s glass transition temperature (Tg). Additionally, as expected the softening occurs at lower temperatures for measurements acquired at lower frequencies.
AFM-nDMA data from Fig. 3 was used to generate the master curve of loss tangent for FEP. For both bulk DMA and AFM-nDMA data, we followed the industry standard operating procedure …

The glass transition temperature can be determined using either the storage modulus, complex modulus, or tan δ (vs temperature) depending on context and instrument; because these methods result in such a range of …
The storage modulus, either E'' or G'', is the measure of the sample''s elastic behavior. The ratio of the loss to the storage is the tan delta and is often called damping. It is a measure of the energy dissipation of a material. Figure 2.
Typical DMA thermogram of an amorphous thermoplastic (polycarbonate). Storage Modulus (E'') and Loss Modulus (E'''') and Loss Factor tan (delta) are plotted as function of temperature. The glass transition temperature of Polycarbonate was detected to be around 151°C (evaluation according to ISO 6721-11)

Dynamic mechanical analysis (DMA) is a versatile tool for determining the dynamic characteristics of materials. It can measure the properties of a range of materials, such as storage modulus …
This novel, non-resonant measurement is embedded in a force curve and typically occurs at a series of frequencies to provide spectra of storage modulus, loss modulus, and loss tangent. By using tailored probes and …
An important technique used to assess the glass transition within polymeric materials is dynamic mechanical analysis (DMA). A DMA temperature sweep provides information on the storage …
DMA measures stiffness and damping, these are reported as modulus and tan delta. Because we are applying a sinusoidal force, we can express the modulus as an in-phase component, the storage modulus, and an out of phase component, the loss modulus, see Figure 2. The storage modulus, either E'' or G'', is the measure of the sample''s elastic behavior.
