Porous polymeric membrane has gained attention from various technologies demanding energy storage, molecular separation, and catalyst. The continuous network is formed using the thiourea bonding and synthesized through the organic sol-gel transition. The thiourea has the property of binding anions via the acidity of hydrogen bonding according to the alkyl group. The nanoporous thiourea based membrane can be made by spinodal decomposition which is rinsing a porogen polymer that does not participate in the reaction In this study, we prepared thiourea-based ionogel electrolytes using spinodal decomposition mechanism for the flexible and porous polymeric membrane which can be controlled the pore size depending on molecular weight of porogen and ratio. The pore size of the synthesized polymer was measured by a dynamic light scattering (DLS), Brunauer-Emmett-Teller (BET) and calculated percent conversion using 1H-NMR. Thiourea-based ionogel was studied different types of ionic liquids for ionic conductivity, electrochemical stability through SEM and EIS analysis.
