Self-assembly behaviours of a lipid-mimic brush polymer in thin films and at air-water interface |
| 초록 |
Poly(oxy(11-phosphorylcholineundecylthiomethyl)ethylene) were investigated for the first time in nanoscale thin films as well as at the airewater interface. In thin films, the PECH-C11-PC molecules were found to form a well-ordered, inplane-oriented molecular multibilayer structure in which the bristles made partial interdigitation in the neighbored layers via the favorable interactions of the PC end groups. The brush polymer molecules were further found to favorably form molecular assemblies at the water interface. They initially formed a monolayer assembly in which the hydrophilic backbones were in the extended conformation and the zwitterionic PC ends were anchored at the water interface and the hydrophobic alkylenyl linkers were present over the water surface. This phase underwent a surface pressure-driven structural transformation path way. |
