Applications of x‐ray photoelectron spectroscopy imaging in the analysis of heterogeneous polymer surfaces are evaluated using a sample containing tetrafluoroethylene plasma‐deposited onto polyethylene. The C 1s and F 1s images acquired using non‐monochromatic Mg Kα and monochromatic Al Kα x‐ray sources are used to demonstrate good charge stabilization, as confirmed by small‐area spectra. The use of non‐monochromatic flood sources vs. monochromatic focused x‐ray ray sources for image acquisition is discussed. The use of the valence band region for imaging is also demonstrated.
