中文摘要 | Thin films of poly(methyl methacrylate)/polystyrene (PMMA/PS 80/20 W/W) blend prepared on glass substrate by spin-coating from a cosolvent, chloroform were studied. The formation of regular Voronoi patterns was found under phase contrast microscopy (PCM). It was observed that there were clear concave boundaries in the PCM images by atomic force microscopy (AFM). Although the sample was annealed at 220℃ more than 7 h, no changes of the Voronoi pattern occurred, implying that the phase separation structure in the Voronoi pattern was almost complete during spin-coating process. It was believed that the formation of this pattern was due to the convection during spin-coating procedure.; 国家自然科学基金(基金号20174022); 重大研究计划“理论物理学及其交叉科学若干前沿问题”子课号90103035); 重点基金(基金号10334020)资助项目 |
