| 中文摘要 | the thin films of a symmetric crystalline-coil diblock copolymer of poly(l-lactic acid) and polystyrene (plla-b-ps) formed lamellae parallel to the substrate surface in melt. when annealed at temperatures well above the glass transition temperature of plla block (t-g(plla)), the plla chains started to crystallize, leading to reorientation of lamellae. such reorientation behavior exhibited dependence on the correlation between the crystallization temperature (t-c), the glass transition temperature of ps (t-g(ps)), the peak melting point of plla crystals (t-m(plla)), and the end melting point of plla crystals (t-m,end(plla)). when annealed at (t-c =) 80 degrees c (t-c < t-g(ps) < t-odt, order-disorder transition temperature), 123 degrees c (t-g(ps) < t-c < t-m(plla) < t-odt). 165 degrees c (t-g(ps) < t-m(plla) < t-c < t-m,end(plla) < t-odt), the parallel lamellae became perpendicular to the substrate surface, exclusively starting at the edge of surface relief patterns. meanwhile, the corresponding lamellar spacing was significantly enhanced. |
