A new paper has just been accepted by RSC Advances, written by Richard Plenderleith, Dr. Thomas Swift and Dr. Stephen Rimmer, titled Highly-branched Poly(N-isopropyl acrylamide)s with core-shell morphology below the lower critical solution temperature.
Highly-branched poly(N-isopropyl acrylamide)s in water pass through coil-to globule transitions. Using calorimetry and the colour change of a solvatochromic dye within the polymer, we show that some compositions have biphasic core-shell morphologies, with globular cores and open coil shells. The two-phase structure is favoured by increased branching and arises because the chain ends penetrate only to a limited degree into the polymer coil.
