Analysis of Polystyrene (PS) by XPS

Abstract

We report x-ray photoemission spectra of polystyrene (PS). XPS spectra were measured with the SSI, SSX-100 model, using monochromated Al Kα x-rays. We present the survey spectrum (binding energy range of 0–1100 eV) and a narrow spectrum of C 1s. The polymer is used as a reference to study the influence of PS surface modification by rf plasma for biochemical applications.
