8 Nanofabrication on Reactive Block Copolymer Film …
Fig. 8.4 a AFM height and b FV images (500 nm × 500 nm) of the cyclohexane-treated PS 690 -
b-PtBA 1210 polymer films; c AFM height and d FV images of the cyclohexane-treated PS-b-PtBA
polymer films after hydrolysis; e AFM height and f FV images of the cyclohexane-treated PS-bPtBA polymer films after hydrolysis, reactivation by NHS/EDC and grafting of fluoresceinamine;
g AFM height and h FV images of the cyclohexane-treated PS-b-PtBA polymer films after hydrolysis, reactivation by NHS/EDC and grafting of n-butyl amine. All data has been acquired with a
Si 3 N 4 probe tip in air. By convention, the bright areas in the FV images correspond to low pull-off
forces (several protruding circular areas have been marked with circles to guide the eyes). Slight
off-sets between the height and FV images are the result of the sometime unavoidable sequential
data acquisition
