Location of Deuterated Short Diblock in Binary Blends of Block Copolymer Having Hydrogen Bonding |
| 초록 |
The binary mixture of two block copolymers whose blocks are capable of forming the hydrogen bonding allows one to ontain various microdomains that could not be expected for neat block copolymer. For instance, we reported that the binary blends of symmetric polystyrene-block-poly(2-vinylpyridine) copolymer and polystyrene-block-polyhydroxystyrene copolymer where the hydrogen bonding occurred between P2VP and PHS showed hexagonally packed cylindrical and body centered cubic spherical microdomains. To explain the unexpected results, one should investigate the exact location of short block chains in the interface. For this purpose, we synthesized deuterated polystyrene-block-polyhydroxystyrene copolymer (d-PS-b-PHS) and prepared the mixture of this block copolymer with PS-b-P2VP. Through small-angle neutron scattering, small-angle X-ray scattering and neutron reflectvity, the exact location of shorter dPS block in the mixture near the interface of the microdomains will be investigated. |
