Analysis of Poly(methyl methacrylate) (PMMA) by XPS

We report x-ray photoemission spectra of poly(methyl methacrylate) (PMMA). 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 narrow spectra of C 1s and O 1s. The polymer is used as a reference to study the influence of PMMA surface modification by rf plasma for biochemical applications.
