摘要: A series of polyacrylonitrile-block-polystyrene (PAN-b-PS) and polyacrylonitrile-block-poly(methyl methacrylate) (PAN-b-PMMA) diblock copolymers with PAN volume fraction up to 20% self-assembles in nonpolar selective solvents form cylindrical micelles a core, having contour length varying between less than 1 ion tens micrometers. Micelle characterization by differential light scattering, nuclear magnetic resonance, transmission electron microscopy, atomic force microscopy scanning calorimetry enabled point out the role played crystallinity during micellization, thence suggesting that core crystallization overcomes other factors governing self-assembling processes. © 2008 WILEY-VCH Verlag GmbH & Co.
