Resumen:
This article describes the synthesis and characterization of stimuli-sensitivehybrid films using 2-(diisopropylamino)ethyl methacrylate (DPA), and apolyurethane (PU) base on isophorone diisocyanate. Hybrid films withdifferent amounts of DPA present good film and physicochemical properties.Characterization techniques such as Fourier transform infrared, UV?visible,modulate differential scanning calorimetry, and thermogravimetric analysisreveal chemical interactions between PU and DPA groups. Swelling behaviorof films shows a dependence on DPA content, pH, and temperature anddifferent mechanisms of water uptake in response to pH and temperaturevariations. Hybrid systems would allow controlling water absorption not onthrough pH or temperature but also from the chosen PU/DPA proportion.
