Polymer science is the study of polymers, which are large molecules made up of repeating structural units called monomers. These materials can be natural, like rubber and cellulose, or synthetic, such as plastic and nylon. Polymer science explores how these molecules are formed, their properties, and how they can be manipulated for various applications. Researchers in polymer science investigate the physical and chemical behaviors of polymers to develop new materials with specific characteristics. This field has significant implications in industries like medicine, packaging, and electronics, where tailored polymers can enhance product performance and sustainability.
