Communication: A new strategy toward patterned polymer brushes combining the spatially controlled deposition of poly[(hydroxymethyl-p-xylylene)-co-(p-xylylene)] (1) by chemical vapor deposition (CVD) polymerization of 4-(hydroxymethyl)[2.2]paracyclophane and surface-initiated ring-opening polymerization was developed. Patterns of polymer brushes with thickness between 53 and 538 Angstrom were created. The approach does not require photolithographic tools and has potential applicability to a wide range of different substrates such as glasses, polymers, metals or composites.
