The structure of gelatin–water/oil microemulsion sols and gels. An EPR spin-probe and spin-labelling study
Literature Information
The microenvironments of sols and gels of gelatin in water-in-oil microemulsions formed by sodium bis(2-ethylhexyl) sulfosuccinate (AOT) in isooctane have been characterized by EPR spin-labelling and spin-probe techniques. Using spin-labelled gelatin, incorporated both in sol and gel, the changes in the microstructure(s) around the gelatin have been monitored, at different water and gelatin compositions. Specific locations of the gelatin have been found: some of the gelatin is located at the water/surfactant interface and part in pools of water. Gelatin is not found in the apolar phase. The spin-probe technique, with amphiphilic probes, provides information on changes in the structure of the aggregates as a result of gelatin incorporation. Increased microviscosity, and a tighter packing of the AOT chains is observed, confirming the location of gelatin at the water/surfactant interface. Our results favour a model for the gel structure in which all the gelatin is covered by water and surfactant, with large cavities of polar and apolar solvent.

Physical Chemistry Chemical Physics

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.
