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.[1][2]

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.[3] 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.[4] It may also be used in the formation of AEMs, which can be used in the development of microbial desalination cell system (MDCS).[5]
