Chemists solve long-standing polymer science puzzle

New research by the University of Liverpool's Chemistry Department represents an important breakthrough in the field of polymer science. In their study, Liverpool researchers use mechanochemistry to characterize how a polymer chain in solution responds to a sudden acceleration of the solvent flow around it. This new approach answers a fundamental and technological question that has preoccupied polymer scientists for the past 50 years.

The discovery by Liverpool chemists Professor Roman Boulatov and Dr. Robert O'Neill has significant scientific implications for several areas of physical sciences as well as at a practical level for polymer-based rheological control used in many multi-million dollar industrial processes such as enhanced oil and gas recovery, long distance piping, and photovoltaics manufacturing.

Scientific Implications and Future Research

Professor Roman Boulatov said, "Our finding addresses a fundamental and technical question in polymer science and potentially upends our current understanding of chain behavior in cavitational solvent flows." He further added, "Our paper has important implications for our ability to study non-equilibrium polymer chain dynamics at the molecular length scales, and thus our capacity to answer fundamental questions of how energy flows between molecules and within them, and how it transforms from kinetic to potential to free energies."

The research team plans to focus on expanding the scope and capabilities of their new method and exploiting it to map molecular-level physics that would allow accurate predictions of flow behavior for an arbitrary combination of polymer, solvent, and flow conditions.
