Facile Generation of Nanoporous Organic Frameworks via Simultaneous Phase Separation and Gelation of Covalent Network/Polymer Mixture |
| 초록 |
Nanoporous materials have gained attention for promising future applications such as catalysis and separation. Poly-urea-network(PUN)-based organic sol-gel synthesis was developed as a novel synthetic method to obtain solution-processible microporous covalent molecular network. Recently, a new type of nanoporous polymer called Spinodal Covalent Frameworks(SCFs) was prepared from PUN/polymer blend during organic sol-gel synthesis. Simultaneous progress of phase separation and gelation produces bicontinuous nanostructure. To understand the relationship between polymer and morphology, we investigated phase behaviors of PUN/polymer blends with various polymers. The resultant morphology was found to depend on the physical and chemical properties of the polymers. The results provide general criteria of polymer that optimizes nanoscale architecture required for specific applications including water desalination, batteries, etc. |
