Polymer physics connects the conformations and motion of long molecules to the properties of a material. A polymer can change shape through many segment rotations while its chemical backbone remains intact. This makes the competition between flow and relaxation important: the same chain can behave as a coil in one experiment and an extended object in another. Soft matter includes both these flexible structures and liquid crystals, whose orientational order produces a different route to strong mechanical and optical response.

Polymer physics is a branch of condensed matter physics that focuses on the physical properties and behavior of polymers—large molecules composed of repeating structural units known as monomers. Polymers can include natural substances like proteins and cellulose, as well as synthetic materials such as plastics and rubber. Key areas of study within polymer physics include: 1. **Structure and Morphology**: Understanding the arrangement of polymer chains and how their structure affects properties.
