Effects Of Radiation

To improve the performance of sulfonated polyimide (SPI) membrane, especially to heighten water stability, γ-rays irradiation-induced crosslinking is used to modify the SPI membrane. The effects of radiation crosslinking on SPI membrane are investigated. Their physical properties, membrane morphology, proton conductivity, membrane stability and mechanical property are measured and reported. In this study, 24 hours radiation treatment endow the SPI membrane (SPI-24h) with the optimum performance, remarkably improved the water stability with only slight sacrifice in proton conductivity.

A novel 2D nickel(ii) complex (1) has been successfully synthesized using a 2,2′-bipyridyl, polycarboxylsulfonate ligand H4SBTC and Ni2+ ions. Owing to the presence of abundant water molecules, hydrogen bond networks and other protons, 1 and its hybrid membranes demonstrate high proton conductivity.
