Thermodynamic and Kinetic Aspects of Coassembly of PEOMINUS SIGN PMAA Block Copolymer and DPCl Surfactants into Ordered Nanoparticles in Aqueous Solutions Studied by ITC, NMR, and Time-Resolved SAXS Techniques

Popis výsledku v původním jazyce

The electrostatic coassembly of a block copolymer polyelectrolyte poly(ethylene oxide-block-poly- (methacrylic acid), PEO705MINUS SIGN PMAA476, and oppositely charged surfactant, N-dodecylpyridinium chloride (DPCl), has been investigated by a combinationof isothermal titration calorimetry (ITC), spin-echo NMR spectroscopy, and timeresolved SAXS measurements. The study (i) confirms the conclusions drawn from our earlier study [Macromolecules 2012, 45, 6474] by scattering and microscopy techniques (i.e.,the ITC curves can be interpreted using arguments consistent with conclusions of the earlier study) and (ii) yields new insight into the thermodynamic and kinetic behavior of the self-assembling system. The most important finding obtained by stopped-flow time-resolved SAXS measurements concerns the surprisingly high rate of processes of creation of structurally ordered cores of self-assembled surfactantMINUS SIGN polyelectrolyte nanoparticles (<50 ms).
