32. The samples in acidic buffer were monitored for a longer time than that shown in the figure. The brush in buffer at pH 6.0 fully degraded in 2 months. However, the thickness of sample in buffer with pH 3.0 was unchanged after 2 months.

35. We acknowledge that this experiment does not conclusively rule out contamination via nonpolar materials from air that are then washed off when the sample was incubated in water. This contamination, however, would be slight since thickness does not change appreciably. This experiment also does not probe changes in surface morphology (which are related to change in polymer conformation) which take place over longer length scales.

37. This paper shows that the solvent in contact with the oxidized polyethylene surface has a large effect on the reorientation of these oxidized groups: Holmes-Farley, S. R.; Reamey, R. H.; Nuzzo, R.; McCarthy, T. J.; Whitesides, G. M. Langmuir 1987, 3 (5) 799-815
