Application

Polyetherimide (PEI) serves as a versatile and robust matrix material, widely used for its excellent thermal stability and mechanical properties, in the development of advanced composites and membranes. It finds significant applications in fabricating carbon molecular sieves when blended with polyethylene glycol (PEG), enhancing selective permeability. Additionally, PEI is utilized in creating a variety of composites, such as PEI/BaTi4O9 for dielectric properties, PEI/glass fiber for strength and durability, and nanocomposite membranes like PEI/TiO2-sulfonated polymer for improved filtration and separation processes. Furthermore, PEI forms the backbone of innovative materials such as nanoparticles coated PEI-polyurethane (SiO2/PEI-PU) nanofibrous composite membranes and single-walled nanotubes (SWNTs)/PEI nanocomposites, showcasing its adaptability and critical role in pioneering material science applications.
