Nous avons obtenu et analysé les spectres Raman de polymères en films minces et de la région interfaciale entre des films de polymères lamellaires, en couplant le faisceau laser avec un guide d'onde optique par l'intermédaire d'un prisme. Des informations sur les orientations et la répartition des molécules sont obtenues en modifiant les modes et la polarisation du champ électromagnétique incident. Nous présentons les résultats concernant différents films et leurs interactions interfaciales.By coupling laser light with a prism into an optical waveguide, we have observed and analyzed Raman spectra of thin polymer films, and of the interfacial region between laminate polymer films. Both orientational and spatial informations are obtained by o...
