XPS Study of the Chemical Structure of Plasma Biocopolymers of Pyrrole and Ethylene Glycol

Figure 4

High-resolution C1s scan. The chemical formula represents the possible union of three pyrrole and three ethylene glycol molecules in PEG/PPy/I. The legends indicate the probable chemical states with their approximated formation energy in eV. The red legends indicate chemical states that do not belong to the monomers.
