The enhancement of Microphase Separation by Hydrogen Bonding |
| 초록 |
Reducing the size of block copolymer microdomains is one of the hottest issues because of strong demand in industrial applications to lithography, nano-patterning, and nanostructured materials. We utilized hydrogen bonding between N-(4-aminomethyl-benzyl)-4-hydroxymethyl-bezamide (BA) and urea (U) at the interface of polystyrene-block-poly(methyl methacrylate) copolymer (PS-PMMA) microdomains. For this purpose, the amino terminated PS was first reacted with BA, followed by the addition of 4-pentynoic acid to PS-U-BA resulting in alkyne-terminated group. Then, by the azide-alkyne click reaction between PS-U-BA-alkyne and PMMA prepared by ATRP, PS-U-BA-PMMA is synthesized. The effect of the hydrogen bonding on the phase behavior is investigated. |
