Abstract
|
Infrared spectroscopic ellipsometry (IRSE), infrared transmission spectroscopy, and theregularized method of deconvolution are applied cooperatively for the analysis of the process of mixingin thin double layers (about 100 nm each) of poly(<I>n</I>-butyl methacrylate) (PnBMA) and poly(vinyl chloride)(PVC) on gold. For the first time thin polymeric double layers in the nanometer range and the annealinginduced interactions have been investigated by IRSE. Spectral changes in the ellipsometric spectra ofthin films are compared to those observed in the infrared absorbance of 5-10 <IMG SRC="/images/entities/mgr.gif">m thick films of the samepolymers. The stabilization of conformational states of side-chain ester groups has been revealed afterthe annealing process and cooling to room temperature. The formation of hydrogen-bond-type interactionsbetween the PnBMA carbonyl and PVC methine groups in the annealed double layer is found. Withincreasing annealing time the PnBMA/PVC sample progressively approaches a mixed homogeneous state.
