Abstract
End-tethered chains made of an adsorbed diblock copolymer of polystyrene (PS)−polyisoprene (PI) bearing an end-segment including a Ge atom are built by the Langmuir−Schaeffer technique. They are studied both in the dry state and in a good solvent for the PI chain using grazing incidence X-ray standing waves. The analysis of the signal provides a direct measurement of the end-segment distribution which is found to be singular and mostly localized to a plane in the dry case. In the good solvent case, end-segments are found to span the entire assembly and compare very well with results obtained by Kreer et al. [Kreer, T.; Metzger, S.; Müller, M.; Binder, K.; Baschnagel, J. J. Chem. Phys. 2004, 120, 4012].
