Abstract

SANS measurements show a temperature induced transition from a compact to a more swollen liquid crystalline SDS/decanol/water phase in the presence of a certain amount (3% by weight) of the oppositely charged polyelectrolyte poly(diallyldimethylammonium chloride) (PDADMAC). DSC measurements indicate a phase transition in a specific temperature region. Additional measurements show that the phase transition temperature is shifted to higher values by increasing the PDADMAC concentration. This implies that the transition from a “normal” swollen LC-phase to a more compact non-swollen LC-phase can be induced at room temperature by adding a critical amount (5% by weight) of PDADMAC.

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.
