22. At this point, it is relevant to refer to the work of Fredrickson and collaborators [G. Fredrickson et al., Macromolecules 25, 2882 (1992)] who showed theoretically that there exists a selected wavelength for the deformation of a polymer brush (long-range fluctuations are suppressed by grafting as are very short-range deformations by capillary).
