General description

Poly(ethylene oxide) (PEO) is a synthetichydrophilic polymer available in several molecular weights. It can be obtained by the ring-opening polymerization ofethylene oxide. It is a semicrystalline polymer with high ionic conductivitycommonly used as a solid polymer electrolyte.

Application

Poly(ethylene oxide) can be used to prepare polymer electrolyte systems for energy storage and conversion devices such as all-solid-state lithium-ion batteries (ASLBs).

This biocompatible polymer can be widely used in the field of biomedical research and tissue engineering. For example, it can be used in the fabrication of biodegradable polyurethane/graphene oxide scaffolds.

Previous studies have demonstrated that Separan AP-30, a drag-reducing polymer, significantly decreased the formation of atherosclerotic plaques in rabbits fed a high-cholesterol diet. Furthermore, Separan AP-273, a polymer similar to but longer than Separan AP-30, markedly increased cardiac output in
