제목 Thermal Annealing Effect on Phase Transition of Block Copolymer Mixtures
초록 We investigated the phase transition for block copolymer (BCP) mixtures composed of a symmetric polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) and phenyl acetamide derivatives. An annealing temperature dependence for BCP mixtures with 4-hydroxyphenyl acetamide (HPA) indicates that the complex by H-bonding mediation between the nitrogen units of P2VP block and hydroxyl group in the HPA enhances nonfavorable segmental interactions between two block components during heating process. Hence, H-bonding mediation is turned out to be critical to control over transition behavior for BCP mixtures with the functional molecules.
