일반 설명
Pyromellitic dianhydride is a dianhydride class of monomers commonly used in the preparation of polyimides polymers which are used in aerospace, electronics, and automotive industries because of their excellent thermal stability, high mechanical strength, and inherent flame resistance. It is also used in the synthesis of thermoplastic polymers such as polyesters and polyethers, as well as plasticizers and epoxy resins. Additionally, PMDA serves as a curing agent for epoxy resins. Epoxy resins are widely used in adhesives, coatings, composites, and electrical insulation materials.
Pyromellitic dianhydride (PMDA) is an acidic anhydride that can be used as a repair agent and as a chain extender in the formation of polyethylene terephthalate (PET) based chain extensions. It is mainly used in the production of thermoplastics and other coating applications.

A high-barrier polyimide (2,7-CPI) was synthesized through the polymerization of pyromellitic dianhydride (PMDA) and a novel diamine (2,7-CDA) containing carbazole moiety. The synthesized diamine and polyimide were fully characterized by elemental analyses, FTIR and NMR. The 2,7-CPI displays very attractive

Carbon-based materials with different morphologies have special properties suitable for application in adsorption, catalysis, energy storage, and so on. Carbon spheres and carbon monoliths are also nanostructured materials showing promising results. However, the preparation of these materials often require the
