Quantitative-Analysis of Polymer Surfaces and Films Using Elastic Recoil Detection Analysis (Erda), Fourier-Transform Infrared-Spectroscopy (FTIRS), and High-Resolution Electron-Energy-Loss Spectroscopy (HREELS)
A method of applying HREELS as a quantitative analysis technique to the study of polymer surfaces is presented. For this purpose, a series of random polystyrenes consisting of perdeuterated and hydrogenated monomers randomly distributed along the chains was synthesized and characterized by ERDA and FTIRS. Compositions determined from HREEL spectra of random polymers were then compared to those determined from ERDA and FTIRS. The agreement between HREELS results and the composition obtained by the other techniques is good : the isotropic composition of the polymer surface can be determined with an accuracy of the order of 5%.
