General description

Poly(propylene glycol) bis(2-aminopropyl ether) is a flexible hydrophobic polymer widely used in the preparation of epoxy resins.

Application

Poly(propylene glycol) bis(2-aminopropyl ether) (PEA) can be used as an additive:
  • To passivate the trap states(surface and grain defects) in perovskite solar cells. PEA helps to improve the stability and efficiency of devices.
  • To fabricate nanocomposites for CO2 capture. The ether group of PEA acts as a proton acceptor that helps to improve the thermal stability and amount of CO2 captured.
