제목 Aspect Ratio Effect of Nanorod Surfactants on the Shape and Internal Morphology of Block Copolymer Particles
초록 Controlled assembly of nanoparticles within a polymer matrix is of particular interest in the case of nanorods (NRs), because the collective electrical and optical properties of their organizations strongly depend on both their shape and directional assembly. The effect of aspect ratio (AR) of NR surfactants on the shape and internal morphology of block copolymer (BCP) particles was systemically investigated using polystyrene-b-poly(4-vinylpyridine) and CuPt NRs with different AR values ranging from 1 to 15. The positioning of the NRs inthe BCP particles was dependent strongly on their AR values. It enabled the modulation of the interfacial properties at selective locations on the BCP particles, thus producing interesting morphological transition of the BCP particles such as convex lens-shaped particles with regularly arranged channels.
