title: Thermoresponsive coatings strongly adhering to (semi)conducting surfaces.
abstract: Thermoresponsive brushes have been efficiently grafted onto (semi)conductive surfaces by a two-step process. In the first step, poly(N-succinimidyl acrylate) chains have been chemisorbed onto silicon or stainless steel by the electrografting method. Then, these modified electrodes were immersed in isopropylamine in order to transform the grafted chains to the thermoresponsive poly(N-isopropyl acrylamide). The thermal response of these brushes has been shown by AFM. This straightforward grafting process is quite attractive for surface modification in confined media and is thus promising for microfludics application.
