Applications of internal friction technology in the study of soft matter

Soft condensed matter physics has become a fast developing and important subject in physics. Understanding the complex non-equilibrium dynamics and pattern of movement is the key to many macroscopic properties of soft materials. Internal friction, as a powerful experimental technique for the study of defects and mechanical properties of materials, is sensitive to complex phase transformations and relaxation dynamics in condensed matter. In this work we demonstrate the applications of internal friction technology in the study of soft matter based on our recent work. With the emergence and development of new measurement methods and techniques and new internal friction theories, we believe that internal friction will play an increasingly important role in the investigation of condensed matter physics and materials science.
