Abstract

When a polymer collapses in a mixture of two competing good solvents, the phenomenon is termed as co-non-solvency that is driven by preferential adsorption of the better cosolvent with the polymer. High pressures, however, significantly reduce this preferential binding and thus destroy co-non-solvency of PNIPAm.
