We report on the preparation of temperature sensitive surfaces by plasma polymerization (pp) of N,N-diethylacrylamide (DEA). The chemical composition of the resulting ppDEA films was characterized by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. A higher retention of monomer structure could be achieved by reducing the plasma input power. The temperature sensitivity...
The kinetics of moisture sorption/desorption in poly(terephthalate-co-phosphate) thin films was investigated in situ at T=25°C using optical waveguide spectroscopy (OWS). At low water activities, Fickian diffusion was observed for the initial phase of the sorption process, while at high activities, due to the clustering of water, a complex sorption behavior was found. The moisture sorption isotherms...
