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.
提出了一种新的、简单有效的通过电沉积和自组装制备二元图案刷的方法。该技术涉及使用电化学将链转移剂 (CTA) 固定在图案化导电基底上，通过可逆加成-断裂链转移 (RAFT) 过程介导表面引发聚合 (SIP)。然后，通过原子转移自由基聚合 (ATRP) 硅烷引发剂的自组装对非电图案化表面进行回填，下一个刷的聚合在那里引发。RAFT 和 ATRP 等技术的使用众所周知可以提供受控的聚合机制，这对于生成二元图案刷非常有利。傅里叶变换红外成像 (FT-IR) 被用于分析这些薄膜。
