Nanoporous thin films from supramolecular interactions of Poly(ethylene oxide) Dendrimer and Polystyrene |
| 초록 |
Supramolecular assembly of end-functionalized polymers, forming block copolymer-like supramolecules based on acid-base interaction, has utilized as a simple and facile method for generating functionalized nanoporous thin film. Here, the binary blend film of aminated poly(ethylene oxide) dendrimer (APEO-G) and sulfonated polystyrene (SPS) at a stoichiometric composition after benzene/water solvent vapor annealing exhibits spherical domains in multi-layers over large area. By controlling the number of end-functional arms of dendrimer via divergent ring-opening polymerization of ethylene oxide as well as the molecular weights of SPS, domain sizes can be controlled ranging from approximately 35 to 131 nm. Our supramolecular-assembly system provides an alternative approach for fabricating a functional nanotemplate by easily etching domains with selective solvent treatment, remaining functional groups at the pore surfaces. |
