Polymer physics is a subfield of materials science that is concerned with the physical behavior and properties of polymer materials, which are long-chain molecules made up of repeating subunits. This specialized skill involves studying the structure, properties, and behavior of polymers at the molecular level, as well as investigating methods for synthesizing, processing, and manipulating polymers to optimize their properties for various applications. Polymer physicists may work in diverse industries such as medical devices, electronics, aerospace, and energy, among others.
