Block copolymers having self-assembled properties have been widely applicable to lithography, nano-patterning, and nanostructured materials. Hydrogen bonding could affect the sizes and types of block copolymer microdomains. Here, we utilize the hydrogen bonding between N-(4-aminomethyl-benzyl)-4-hydroxymethyl-bezamide (BA) and urea (U) in polystyrene-block-poly(methyl methacrylate) copolymer (PS-PMMA). For this purpose, the amino terminated PS was reacted with BA, followed by the addition of 4-pentynoic acid to PS-U-BA resulting to alkyne-terminated group. Then, through 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. |
