Novel Complex Self-Assembled Morphologies of an Asymmetric A3B3C3 Star Polymer in Nanoscale Thin Films: Synchrotron Grazing Incidence X-ray Scattering Analysis |
| 초록 |
An asymmetric nine-arm star polymer, PS3-PMOS3-PI3 was synthesized, and the details of the structures of its nanoscale thin films were successfully investigated for the first time by using in-situ grazing incidence X-ray scattering (GIXS) with a synchrotron radiation source. Our quantitative GIXS analysis showed that thin films of the star polymer molecules have very complex but highly ordered and preferentially oriented structures. The structure undergoes a partial rotational transformation process at temperatures during heating. These interesting and complex self-assembled nanostructures are discussed in terms of phase separation, arm number, volume ratio, and confinement effect. |
