Introduction

The dynamic mechanical test provides three major parameters: (i) Storage modulus: it is the amount of the maximum energy stored in the polymer material during one cycle of oscillation. It also provides the information regarding the stiffness behavior and load-bearing capability of. Typical tests in this field are used for investigating the softening or melting behavior of samples when heated; or solidification, crystallization, or cold gelation when cooled. The complex viscosity, often used instead of the complex modulus, is the complex modulus divided by the applied frequency.
