Dynamic mechanical analysis (DMA) is a basic tool for the characterization of viscoelastic materials, particularly polymers. Applying an oscillatory force to a material, its response can be measured, calculating the viscosity and the stiffness related to temperature, time, or frequency. In addition, DMA can provide information on the thermal transitions of polymer-based systems. The present chapter provides the readers with notes on reasons for using DMA for polymeric biomaterials characterization. After a short overview on the main characteristics of the instrument, examples of possible characterizations performed on different polymers are reported, evidencing the test protocol and the possible outputs that can be obtained.
