General description

Polyetherimide (PEI) is a thermoplastic polymer, containing cyclic amide. PEI is a polyimide condensation polymer derived from the bifunctional carboxylic anhydrides and primary diamines.[1]

Application

Polymer blends of PEI and polyethylene glycol (PEG) have been used to prepare carbon molecular sieves.[2] PEI has been used as matrix in the fabrication of various composites:
  • PEI/ BaTi4O9 composites,[3]
  • PEI/glass fiber composites,[4]
  • Nanocomposite PEI/TiO2-sulfonated polymer membranes,[5]
  • Nanoparticles coated PEI-polyurethane (SiO2/PEI-PU) nanofibrous composite membranes,[6]
  • Single walled nanotubes (SWNTs)/PEI nanocomposites.[7]
