Application

Imidazolium modified PPO with liquid ionic graphene oxide can be used as an anion exchange membrane (AEM) composite with a peak power density of 136 mW cm−2 for use in the fabrication of high performance fuel cells. It may also be sulfonated to form a long chained polymeric structure with an efficiency of 81.8% at a current density of 120 mA cm−2 for potentiall use in vanadium redox flow batteries (VRFBs) as effective energy storage systems. It may also be used in the formation of AEMs, which can be used in the development of microbial desalination cell system (MDCS).

General description

Poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) is an anion exchange membrane (AEM) material that is mainly used as a cross-linker in which the methyl groups are used to bond with ultraviolet (UV) excited ketones.
