Polyimide refers to a class of synthetic polymers characterized by imide linkages within their repeating units. These high-performance materials exhibit exceptional thermal stability, chemical resistance, and mechanical properties, making them suitable for demanding applications. Their strong intermolecular forces contribute to high glass transition temperatures, excellent dimensional stability, and low coefficient of thermal expansion. The polymer's versatile nature allows for customization, leading to variations in their properties depending on the specific monomers and synthesis processes. They are often used as thin films, coatings, adhesives, and in composite materials across various industries including electronics, aerospace, and automotive.
