Percolated microporous network nanocomposite through gelation of nanoparticles consisting of microporous organic nanoparticles and polyimides |
| 초록 |
Percolated microporous network nanocomposite consisting of microporous organic nanoparticles and polyimide was synthesized. 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. The microporosity of synthesized nanocomposite was characterized under carbon dioxide isotherm at 273K and their permeability of the membranes to small molecules such as water, 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). |
