英文摘要	he orientation transition and self-epitaxial crystallization of all-conjugated diblock copolymers poly(p-phenylene)-block-(3-hexylthiophene) (ppp-b-p3ht) were systematically investigated by in situ temperature-resolved two-dimensional grazing incidence x-ray diffraction (2d gixd) in step-by-step heating and cooling process. b39t18 was selected; the results of 2d gixd showed that the ppp block crystal adopted a face-on orientation while the crystallization of p3ht block was hindered in as-casted films. three different molecular orientations transition were obtained in self-epitaxial crystallization circles. first, p3ht crystallize with edge-on during the heating process and induced the ppp blocks crystallized with edge-on during the cooling process. then, the as-casted film was heated in the melting temperature region of ppp blocks and isothermally crystallized. the partial melting of ppp blocks promoted the p3ht blocks crystallize in a face-on due to the steric limitation effect; ppp blocks crystallized with a face-on via the self-epitaxy during cooling. furthermore, the face-on transformed to thermodynamically stable edge-on in the melt annealing process.
