Description
Using quasi-elastic neutron scattering, we study the pressure-dependent hydration behavior of an aqueous poly(N-isopropylacrylamide) solution during heating through its cloud point (CP). At high pressure, the hydration water diffuses more rapidly than at low pressure, which indicates enhanced hydrophobic hydration. An abrupt dehydration, mainly of the hydrophobic groups, is observed at the CP at low pressure, whereas both hydrophilic and hydrophobic groups dehydrate gradually at high pressure.
