SERS Study of Polymer on Metals .5. Chemisorption and Reactions of Acrylonitrile and Poly(Acrylonitrile)
Surface enhanced Raman scattering (SERS) studies of chemisorption of acrylonitrile and poly(acrylonitrile) on Ag are presented. The SERS spectra obtained at room temperature with low laser power irradiation are markedly different from normal Raman spectra of neat acrylonitrile and poly(acrylonitrile). This is ascribed to surface reactions after adsorption. Under high laser power irradiation, the SERS spectra show graphitic formation. When the temperature is raised, graphitization of poly(acrylonitrile) on the Ag surface is nearly complete. The reaction mechanisms consistent with the spectral results are proposed.
