Polymer, Water, and Salt Partitioning in Complex Coacervates Characterized by Femtosecond Stimulated Raman Microscopy

open access: yesChemistry–Methods, EarlyView.
The partitioning of polymer, water, and salt within complex coacervates formed by the polyelectrolytes poly(diallyldiemthylammonium chloride) and poly(4‐styrenesulfonate) is investigated using femtosecond stimulated Raman microscopy (FSRM). With FSRM, small sample volumes (≈20 μl) are characterized in a few minutes. Complex coacervates can form through
