Ionic membrane are a critical component of several energy conversation technologies (fuel cell, electrolyzer, metal-ion and redox flow battery, reverse electrodialysis (RED)). In the frame of the ANR CELLOSMO, we are interested in the elaboration of hybrid ionic membrane for blue energy conversion, a renewable and non intermittent energy source originating from fresh (river) and salty water (sea, brine). Our material chemistry strategy relies on using nanocellulose as a biosourced nanostructured scaffold once hydrated, and to graft onto it reactive copolyelectrolytes which can bring the ionic transport properties. The purpose of the present job offer is to develop a library of relevant copolymers.
Goals. Selection of adequate comonomer pairs to have a reactive copolyelectrolyte toward cellulose surfaces and investigation of the influence of their architecture onto the resulting hybrid ionic membrane properties
