Monovalent selective cation exchange membranes could play an important role in balancing the K + /Na ratio agricultural feed streams to prevent toxic effects of excess Na plant and soil systems, especially greenhouses dry areas. A polyelectrolyte complex polystyrenesulfonate polyvinylamine monomer 1:2.5 is hot-pressed form a dense saloplastic. The plastic takes up 42% w/w water when equilibrate...

Membranes made up of composite materials have shown promising advantages for application in alkaline fuel cell anion exchange membranes. In this study, a general method is employed to improve the overall performance and properties membranes by making use polyethersulfone quaternized with imidazolium groups blended functionalized graphene oxide inorganic filler (ImGO). The polymer matrix yielded...

Recently there has been considerable interest in the utilization of covalent-organic frameworks (COFs) as ion-exchange membranes. While rapid ion conduction is experimentally observed COF membranes, underlying mechanism remains elusive. Herein, we report a molecular simulation study on chloride (Cl−) four membranes functionalized with quaternary ammonium groups (QA-2, QA-4, QA-6 and QA-EO) diff...

The aim of this study is to calculate the through-plane thermal conductivity commercial polymeric ion-exchange membranes. Different membranes were considered influence membrane properties on values. In particular we focused reinforcement, ion exchange capacity and density thickness. For purpose, use a simple experimental setup numerical simulation estimate from temperature profiles. Once system...
