Supramolecular assembly of functionalized polymers is considered as a proper replacement of block copolymer for creating ordered nanostructure. Although these supramolecules show unusual characteristics due to their non covalent interaction between two blocks, few studies on the supramolecules based on functionalized polymers have been reported. In this study, a binary polymer blend system with ionic interaction between mono-end-sulfonated polystyrene (SPS) and mono-end-aminated polybutadiene (APB) was prepared, and the change of bulk morphology was examined as functions of blend ratio and thermal annealing temperature. The unique morphology was observed at a blend ratio of SPS/APB=70/30 (w/w), which has not been observed in block copolymer systems. Moreover, when the morphology of thin film was compared with that of bulk, it is different from that of bulk because supramolecular assembly in 2D confined geometry system is affected strongly by the surface tension and film thickness. |
