anus Bottlebrush Block Copolymers : A Universal Strategy Enabling Access to Ultra-Small Feature Size Phase Separation
发布时间:2017-12-04 阅读量:

The phase separation of block copolymers has been widely investigated in past few decades and the challenge lies in achieving ultra-small feature size phase. Herein, we report a universal strategy to access ultra-small feature size phase separation by using Janus bottlebrush copolymers (BBCPs). A series of branched macromonomers (BMMs) with different polymer combinations were polymerized by ring-opening metathesis polymerization to afford Janus BBCPs. Different polymer combinations were applied including PDMS, PLA, PS PtBA and PEG. The simple synthetic procedure and incorporation of readily accessible polymers lend wide applicability to this method. Ultra-small feature size phase separation was demonstrated by a PDMS-branch-PLA Janus BBCP.
