| 英文摘要 | Tensile deformation behaviors of pre-oriented poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) films annealed at different temperatures with or without beta-form structures were investigated using the in-situ small and wide-angle X-ray scattering techniques, as well as DSC and SEM. The sample with beta-form structure showed better ductility. It is convinced that the system can be viewed as a highly stretched and entangled network embedded in highly oriented fibrils being composed of shish-kebabs. Compared with sample without 13 structure, a tentative deformation mechanism for the sample with 13 structure was proposed in this paper, which we believe would shed light on the relationship between 13 structure and mechanical property of PHBV film. The important role of beta-form played in the stretching process of pre-oriented film was also proposed for the first time, in which we stress the role of beta-form structure in stabilizing the ordered microstructures and thereby improving the mechanical properties of the material. |
