Polymer physics
  • 1. Polymer physics is the branch of physics that studies the physical properties and behavior of polymers, which are large molecules composed of repeating structural units. Understanding the properties of polymers is crucial in various fields such as materials science, biophysics, and chemical engineering. Polymer physicists investigate the structure, dynamics, and mechanical properties of polymers, often using techniques such as rheology, microscopy, and spectroscopy. By studying polymer physics, researchers aim to develop new materials with tailored properties, improve processing techniques, and gain insights into biological systems and complex fluids.
