Nanoporous Bicontinuous Structures via Addition of Janus-Type and Thermally-Stable Nanoparticles within Block Copolymer Templates |
| 초록 |
Herein we fabricated the bicontinuous structures from nanocomposites of PS-b-PMMA block copolymer and the thermally stable Au nanoparticles (Au NPs). The surface property of Au NPs was controlled with ligands containing various compositions of PS and PMMA so that the resulting Au NPs were selective to PS or PMMA block, or neutral to both blocks. The Janus-type Au NPs were also prepared by coating the surface of Au NPs with equimolar mixtures of PS and PMMA selective ligands. Consequently, it was found that the morphological behaviors of thermally-annealed nanocomposites containing Janus-type Au NPs and PS-b-PMMA were dramatically different from the case of neutral Au NPs. With increasing the amount of Janus-type Au NPs, a transition from lamellar to bicontinuous structures was observed, whereas the neutral Au NPs were aggregated within the PS-b-PMMA. Furthermore, the nanoporous bicontinuous thin films were fabricated and the morphological behaviors were investigated by GISAXS analysis. |
