Thermodynamics of polyNIPAM -- simulation study — •Vladimir Palivec, Denis Zadrazil, and Jan Heyda — University of Chemistry and Technology, Prague, Czech Republic

Among thermoresponsive polymers, Poly-N-isopropyl acrylamide (PNIPAM), plays a prominent role, both in simulations, theory, and in applications. Nevertheless, the microscopic description of a PNIPAM chain collapse transition above the LCST is still puzzling and challenges the computational chemists for last decades. In this contribution, we have employed large-scale atomistic computer simulations of single PNIPAM chain in explicit water. We have analyzed swollen-to-collapse transition thermodynamics and the values were compared with in house performed experimental data, such as calorimetric or volumetric.
