Microporous network nanocomposite consisting of microporous organic nanoparticles and polyimide was synthesized that are potentially applicable in mass transport membrane. Nanoparticles were synthesized from tetrakis(4-aminophenyl)methane and hexamethylene diisocyanate by organic sol-gel polymerization to produce the 3D microporous organic molecular network. The nanoparticles dispersions were mixed with poly(amic acid) using various dianhydrides and diamines. Casting onto the glass plate followed by thermal curing gave nanocomposite film. We investigated on the morphological structures subjected to different reaction time and composition of nanoparticles. Continuous interconnected nanostructures in polymer matrix were prepared by controlling spinodal decomposition and reaction between numerous reactive amino and isocyanato functional groups of nanoparticles and polyimide chains. The microporosity of synthesized nanocomposite was characterized under carbon dioxide isotherm at 273K and their permeability of the membranes to small molecules such as helium, carbon dioxide, and nitrogen was also measured.This work was supported by the Korea Science and Engineering Foundation (KOSEF) grant [2010-0026421] funded by the Korean government (MEST).
