Fluorocarbon–hydrocarbon microblock copolymers –(CF 2 ) n –(CH 2 ) m – ( n = 4, 6, 8; m = 6, 8, 10) were synthesized. Binding energies of the C 1s and F 1s peaks of these copolymers were measured using x‐ray photoelectron spectroscopy. The binding energy of the C 1s peaks of the carbon atoms of the hydrocarbon segments was set at 285.0 eV as the binding energy reference. Unexpectedly, the binding energy of the C 1s peak corresponding to the CF 2 group of the microblock copolymers was determined to be ∼291.4 eV, which is ∼0.8 eV lower than that of the CF 2 group of tetrafluoroethylene.
