In the field of environmental protection, the efficient separation of oil and water is required with appropriate surface chanmical characteristics and selective separation. Thiourea-based 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 extractioned porogen materials that do not participate in the reaction. In this study, we prepared thiourea-based nanoporous membrane using spinodal decomposition mechanism for the flexible and porous polymer membrane which can be controlled the pore size depending on a ratio of the porogen materials. The pore size of the synthesized polymer was measured by a dynamic light scattering (DLS), Brunauer-Emmett-Teller (BET). The extractioned porogen was identified by the IR and SEM measurements.
