摘要: Abstract Micelle structural properties were determined for five poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) triblock copolymer solutions at 25°C by using light scattering techniques. Size distributions the Pluronic series P103, P104, P105, F108, and P123 found from dynamic scattering. Aggregation numbers both static determined, results are interpreted fundamental hydrodynamic statistical thermodynamic models. The trends in aggregation behavior discussed terms of surfactant composition. For a fixed poly(propylene content, surfactants with higher content to be less aggregated. oxide)/poly(propylene ratio, molecular weight more These shown agreement previous self-consistent mean-field calculations same polymers compared “star” “brush” model predictions effect chain length on thickness micelle corona.
