Novel proton-conducting materials based on a polyethylene terephthalate track-etched membrane modified with an N, P-containing ionic liquid

The development of novel membrane materials for hydrogen fuel cells, a promising environmentally friendly technology, represents relevant research task. In this work, we propose an approach to creating proton-conducting membranes from industrial polyethylene terephthalate (PET) dielectric track-etched film. An N, P-containing ionic liquid was used as modifying agent, whose polymerization carried out directly in the PET pores. obtained using directed synthesis organophosphorus compounds elemental phosphorus via Trofimov-Gusarova reaction developed at A.E. Favorsky Institute Chemistry Siberian Branch Russian Academy Sciences. properties were characterized by NMR and IR spectroscopy. application onto shown yield material exhibiting required mechanical parameters operation membranes. demonstrate high proton conductivity 77.76 mS·cm-1 353 K. seem thus contributing effective alternative energy sources.
