Supramolecular Thin Film of End Functionalized Polymer blends Upon Solvent Annealing |
초록 |
Supra-molecular assembly relying upon non-covalent bonds of two end-functionalized polymers offers a great opportunity not only for constructing nanoscale structures reminiscent of conventional block copolymer morphologies but also for tailoring surface properties by facile separation of the two polymers after assembly. Here we report the solvent vapor driven formation of supra-molecular nanostructures in a binary polymer blend consisting of complementarily end-interacting two species of polymers, mono-end-sulfonated polystyrene (SPS)/mono-end-aminated poly(ethylene oxide) (APEO). A variety of blend morphologies were obtained, depending on blend compositions as well as ratio of mixture of solvents. At the stoichiometric composition of the two polymers, a blend film exhibited an interesting nanoporous structure in which approximately 20 nm circular holes were pseudo-hexagonally organized over very large area. |
