Microstructural description of ion exchange membranes: The effect of PPy-based modification

Properties of ion exchange membranes (IEMs) both cationic and anionic were widely analysed before after chemical. The modification aims to reduce the crossover phenomena typically observed in RFBs by incorporating polypyrrole (PPy) at inner commercial IEMs. In this work, we have explored insight structural generalized conductivity considerations its implications terms physicochemical characteristics. Transport Structural Parameters (TSP) been obtained from electrolyte concentration dependencies (NaCl, work). AEMs successfully increased their specific (between 2.5 3.9 times) whereas CEMs slightly decreased 1.3 2 times). This approach was useful for description membrane electro-transport using so-called two-phase model which considers an IEM as heterophase system (particularly, gel interstitial phase) arrangement. almost doubled internal microphase arrangement parameter (α). A established applied better understand behaviour polymerization. Up 3.5 times diffusion coefficient PPy modification. Finally, based on TSP propose a microstructural IEMs studied work.
