The aggregate structure of a thermoresponsive polystyrene–b-poly(N-isopropylacrylamide)–b-polystyrene (PS–PNIPAM–PS) triblock copolymer was investigated as a function of temperature in aqueous solutions by the combination of small angle neutron scattering (SANS) and dynamic/static light scattering (LS). SANS shows that the system consists of spherical intermicellar aggregates which self-assemble into...
Polystyrene-block-poly(4-vinylpyridine) (PS-b-PVP) forms hairy micelles with PVP and long PS block as the core and corona in toluene, respectively. Diffusion of the micelles in solution in the presence of poly(methyl methacrylate) (PMMA) or polystyrene homopolymer (h-PS), from dilute to semidilute, has been investigated by laser light scattering (LLS). Our results indicate the micelles only exhibit...
The effects of concentration and temperature on dynamics of poly(N-isopropylacrylamide)-graft-poly(ethylene oxide) (PNIPAM-g-PEO) chains in semi-dilute aqueous solution were studied by static and dynamic laser light scattering. The intensity–intensity time correlation function shows a fast and a slow relaxation mode, with line widths Γ f and Γ s , respectively. Γ f is scaled...
