Homo- and mixed polymer brushes prepared by surface-grafting of asymmetric non-sticky/sticky diblock copolymers and their stimuli-responsive behaviors |
| 초록 |
We synthesize a nonsticky/sticky diblock copolymer, poly[styrene-b-3-(trimethoxysilyl)propylmethacrylate] (PS-b-PTMSM), to produce polymer brushes by the grafting-to technique. Uniform coatings of PS brushes are efficiently produced thanks to the multiple reactive groups offered by the sticky PTMSM block and the surface coverage and nanoscopic morphology of the brush layer are adjusted by varying the concentrations of immersion polymer solutions and the immersion time of the substrate. The nanoscopic pattern of PS brushes with the trimethoxysilyl group terminated poly(ethylene oxide)s is utilized further to produce mixed polymer brushes via step-wise coating method. The resultant mixed polymer brushes change their nanoscopic morphology in response to external stimuli. This work was supported by the Korea Science and Engineering Foundation grant [2010-0000282 and 2010-0026421] funded by the Korean government (MEST) and the Program for Integrated Molecular System (PIMS) at GIST, Korea. |
