General description
Poly(ethylene oxide)(PEO) is a high molecular weight, non-ionic water-soluble polymer. It forms agel on hydration and shows good swelling capacity. PEO polymers are non-toxicand widely used in drug delivery systems to enhance drug solubility.
Application
Poly(ethylene oxide) can be used to prepare:
- Bioabsorbable and injectable hydrogels for sustained drug release.
- PEO/graphene oxide composite electrolyte membrane for fuel cells.
- Poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) diblock copolymer. Losartan potassium encapsulated (PEO-b-PCL) copolymer can be used as a drug carrier.
