ABSTRACT

Dynamic mechanical analysis (DMA) is a testing method used to study and characterize viscoelastic properties of polymers and soft materials. In this method, commonly a sinusoidal stress is applied, and the strain of the material is measured. The output determines the complex modulus and other temperature-related properties of the polymer. During the testing, temperature or the frequency of stress of the test sample are often varied, and variations in the complex modulus are measured. This approach can be used to find the glass transition temperature and examine molecular relaxation and particle–matrix interface characteristics. This work deals with the understanding of the theoretical aspects of DMA on polymer analysis, and the testing procedure and measurement of some DMA parameters are discussed.
