Phase behaviour and transition of polymer-brushes on Microcantilevers — •Sebastian Lenz and Jochen Gutmann — Max Planck Institute for Polymeric Research, Mainz

Polymer brush coatings are well known for their ability to tailor surface properties in a wide range of applications. In most cases, brushes are used in solution. Here we show that the micromechanical cantilever (MC) sensor technique is a tool to perform time-resolved physico-chemical investigations of the phase behaviour and phase transition of thin polymeric layers. Complementary to scattering techniques for measuring the thickness, MC sensor technique provides information about changes in the internal pressure of brushes during a phase-transition.
