| 英文摘要 | The morphologies of H-shaped (PS7)(2)PEG(227) (PS7)(2) block copolymer films spin coated onto silicon wafers from different solutions were investigated by means of atomic force microscopy(AFM) and grazing incidence X-ray diffraction. We further compared the crystallization of H-shaped block copolymer with that of poly ( ethylene oxide) ( PEG) homopolymer. The presence of PS block changed the interaction of polymer and substrate. When solvent was tetrahydrofuran, the copolymer dewettecl and crystallized after spin coating when the concentration of solution was 0.1% and 0.25%. As the concentration increased to 0.5%, dewetting was suppressed and two-dimensional spherulites appeared. If toluene was used as solvent, micelles were formed in the solution due to the differences between solubility of PEG and PS block, which changed the final film morphologies. Dendritic crystals containing edge-on and flat-on crystals appeared from the 0.1% solution. More compact crystals appeared while the concentration increased, and large square lamellae was observed after spincoating of 0.5% solution. |
