Small angle neutron scattering of D2O–Brij 35 and D2O–alcohol–Brij 35 solutions and their modelling using the Percus–Yevick integral equation
文献信息
Small angle neutron scattering of direct micelles in binary surfactant–D2O and ternary surfactant–alcohol– D2O systems has been measured. The nonionic surfactant was poly(oxyethylene-23) lauryl ether (C12E23, commercial name: Brij 35) which was used at concentrations far beyond its critical micellar concentration: between 0.1 and 15 mass% (about 1.0×10-3–1.5×10-1 mol l-1). The alcohols were butan-1-ol, pentan-1-ol, hexan-1-ol, and heptan-1-ol at concentrations of about 0.25 mol l-1. The spectra could quantitatively be modelled by the Percus–Yevick integral equation method in combination with a core/shell model yielding detailed information about the size, the (ellipsoidal) shape, the aggregation number, the internal structure and the distribution of the micelles. The ternary systems were modelled with an additional parameter, the partition of the alcohol between the outer aqueous bulk and the inner micellar pseudo-phase. In the case of the pentanol system the partition coefficient inferred from NMR self-diffusion measurements was used to describe the scattering result.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
