Monomers are molecules that have the ability to join with other molecules to form polymers chains. These polymers are essential components of plastics, fibers, and cell walls and they make up a large percentage of natural substances, such as carbohydrates and lipids. By understanding the chemistry of monomers, scientists can develop new polymers with improved properties. For example, polymers with improved durability, strength, and heat resistance can be created. Monomers are also used in the production of emerging materials such as nanomaterials, which can be used for medical, industrial, and electronics purposes.
