Two type Morphological behaviors of Thin Films of an Asymmetric A3B3C3 Star Polymer |
| 초록 |
In situ grazing incidence X-ray scattering (GIXS) measurements and quantitative data analysis were successfully investigated for the first time on thin films of the interesting asymmetric nine-arm star polymer, (polystyrene)3-(poly(4-methoxystyrene))3-(polyisoprene)3. This complex three-phased hexagonal (HEX) structure results from the phase separations of the asymmetric arms under the extreme conditions that their one-end was linked together and the confinement in the thin film by the air and substrate interfaces. Our quantitative GIXS analysis showed structural details of the self-assembly nanostructures of the asymmetric multiarm star which have very complex but highly ordered and preferentially in-plane oriented HEX structures consisting of truncated PS cylinders and PMOS triangular prisms in a PI matrix. At temperatures above 190 °C, this HEX structure undergoes a partial rotational transformation process that produces a 30°-rotated HEX structure. |
