Abstract
Microdomain structures and crystallization behavior of the binary blends consisting of an asymmetric block copolymer and a homopolymer were investigated using small-angle X-ray scattering (SAXS), optical microscope (OM) and differential scanning calorimetry (DSC). Poly(methyl methacrylate)-block-polystyrene block copolymer (PMMA-b-PS) (weight fraction of PMMA=0.53) was mixed with low molecular weight poly(vinylidene fluoride) (PVDF). As the PVDF concentration was increased, the morphological change from a lamellar to a cylindrical structure occurred. The crystallization of PVDF significantly disturbed the orientation of the pre-existing microdomain structure, resulting in a poorly ordered morphology. In the blends, PVDF exhibited unique crystallization behavior due to the PMMA block which is preferentially miscible to PVDF and the space constraint imposed by the microdomains.

비대칭 블록 공중합체와 단일고분자로 구성된 블렌드의 미세 도메인 구조와 결정화 거동을 소각 X-선산란, 광학 현미경 및 DSC를 사용하여 조사하였다. 본 연구에서는 폴리(메틸 메타크릴레이트) 블록의 무게 분률이 0.53인 폴리(메틸 메타크릴레이트)-폴리스티렌 이종 블록 공중합체 (PMMA-b-PS)를 저분자량 폴리(비닐리덴 플루오라이드) (PVDF)와 혼합하였다. PVDF 함량 증가에 따라 블렌드 미세구조가 라멜라에서 실린 더 구조로 전이하였으며, PVDF의 결정화는 결정화 이전에 형성된 미세구조의 배열을 교란시켜 질서도가 낮은 형태를 야기시켰다. 또한, PVDF 결정화 거동은 PMMA 블록과의 혼화성 및 미세 도메인에 의해 부가되는 공간적 제한에 큰 영향을 받았다.
