Nanoparticles of 3D rigid organic network were synthesized from tetrakis(4-aminophenyl)methane and hexamethylene diisocyanate by organic sol-gel method. The nanoparticle dispersions were blended with aromatic polysulfone in DMF and then the mixture solutions coated onto the glass plate. Upon evaporation of mixture solutions, thin film membranes with various microstructure resulted via interplay between phase separation and sol-gel transition behavior. The morphology of the membranes was studied using scanning electron microscopy(SEM) and atomic force microscopy(AFM). The flux and rejection of porous membrane was investigated by filtration of the aqueous solutions containing organic solutes. This work was supported by a Korea Science and Engineering Foundation (KOSEF) grant [2010-0026421] funded by the Korean government (MEST) and the Program for Integrated Molecular Systems (PIMS) at GIST. |
