Abstract

A new, simple, and effective method for preparing binary patterned brushes by electrodeposition and self‐assembly is presented. The technique involves the use of electrochemistry to immobilize a chain transfer agent (CTA) on a patterned conducting substrate that mediate surface‐initiated polymerization (SIP) through a reversible addition–fragmentation chain transfer (RAFT) process. The non‐electropatterned surfaces were then backfilled with self‐assembly of an atom transfer radical polymerization (ATRP) silane initiator where the polymerization of the next brush was initiated. The use of techniques such as RAFT and ATRP is well known to give a controlled polymerization mechanism, which would be of great advantage in generating binary patterned brushes. FT‐IR imaging was used to analyze these films. magnified image

## Abstract A method for growing polymers directly from the surface of graphene oxide is demonstrated. The technique involves the covalent attachment of an initiator followed by the polymerization of styrene, methyl methacrylate, or butyl acrylate using atom transfer radical polymerization (ATRP).
