Abstract
Force microscopy techniques such as atomic force microscopy (AFM), friction force microscopy (FFM), and force modulation microscopy (FMM) were applied to polymer blend and copolymer surfaces to observe phase-separated structures and distinguish the individual components. We observed a continuous phase-separated structure of polystyrene (PS)/polyethyleneoxide (PEO) polymer blend, a micro-phase-separated structure of styrene (S)/butadiene (B) S-B-S-B block copolymer, and islands-sea phase-separated structures of PS/polymethylmethacrylate (PMMA) polymer blend and diblock copolymer with AFM. FFM and FMM were applied to PS/PMMA polymer blend and diblock copolymer, and FFM differentiated PS from PMMA.Keywords
