研究了取向的噻吩基聚合物薄膜的热退火效应。利用聚合物溶液的毛细作用，制备了聚2，5-二(3-烷基-2-基)硫代[3，2-b]噻吩膜(PBTTT)和聚2，5-双(3-烷基-2-基)硫代[2，3-b]噻吩膜(PBTCT)。取向薄膜的光学各向异性在相变温度以下经热退火后得到增强。通过考虑取向膜中的层状堆积结构和相变，讨论了pBTTT和pBTCT光学各向异性的差异。
Thermal annealing effects of the aligned thiophene-based polymer films were studied. Aligned poly2, 5-bis (3-alkylthiophene-2-yl) thieno [3, 2-b] thiophene (pBTTT) and poly2, 5-bis (3-alkylthiophene-2-yl) thieno [2, 3-b] thiophene (pBTCT) films were fabricated by utilizing capillary actions of polymer solutions. The optical anisotropies of the aligned films were enhanced by thermal annealing at temperatures below the phase transition. The differences in the optical anisotropies between pBTTT and pBTCT were discussed by taking the lamellar stacking structures in the aligned films and phase transition into consideration.
