Comparative infrared spectra. ATR-FTIR spectra of MM-45PC relative to membrane composition and NM-45PC are shown. a MM-45PC shows red shift for the cyano group absorption band, indicating an enhanced vibration of Cā”N bond due to the loss of the electron on nitrogen. b MM-45PC shows blue shifts for WāO and WāOāW vibrations, reflecting attenuated vibrations of WāO and WāOāW bonds caused by the transfer of electrons from nitrogen to tungsten. In combination, these shifts in absorption bands demonstrate that under magnetic field influence, electron transfer and an interaction occur between CP4VP and PWA in MM-45PC (dashed lines are used to guide the eyes). ATR-FTIR: attenuated total reflection flourier transformed infrared spectroscopy; CP4VP: ferrocyanide-coordinated poly(4-vinylpyridine); PWA: phosphotungstic acid; NM-45PC: normal-cast membrane with 45āwt% loading of proton-conducting components; MM-45PC: magnetic-cast membrane with 45āwt% loading of proton-conducting components.
