C 1s absolute linear absorption NEXAFS spectra (i.e. optical density per nm thickness sample) of PMMA-on-PAN bilayer, poly(MMA-co-AN) and PECA. These spectra were derived by scaling the originally recorded spectra to match that of the linear X-ray absorption for the elemental composition of the sample derived from literature absorption coefficients (Henke et al., 1993). |
