(a) Patterned diblock copolymer brush formation via spatially controlled dehalogenation and subsequent uniform polymerization of TFEMA. (b) Optical micrograph of the patterned polymer brushes. (c) 19F fluorine and (inset) 12C carbon SIMS scans confirmed localized presence of fluorine (PMMA-b-PTFEMA brushes) atop a uniform MMA polymer brush layer. (d) AFM height profile of the patterned PTFEMA brushes along the dashed line in (b) confirmed patterning and allowed quantification of brush height increase after block copolymerization. Scale bars in (b, c) are 25 μm.
