| 英文摘要 | The effect of PBS on the morphological features of PVDF has been investigated by optical and atomic force microscopies under various conditions. It was found that neat PVDF forms large gamma form spherulites with extraordinarily weak birefringence at 170A degrees C. Adding 30% PBS makes PVDF exhibit intrigued flower-like spherulitic morphology. The growth mechanism was explained by the decrease of the supercooling and the materials dissipation. Increasing the PBS content to 70% favors the formation of ring banded spherulites. Temperature dependent experiments verify the gamma ->gamma phase transition occurs from the junction sites of the alpha and gamma crystals, while starts from the centers of alpha spherulites in the blends. Ring banded structures could be observed in neat PVDF, 70/30 blend and 30/70 blend when crystallized at 155A degrees C, without gamma crystals. The band period of PVDF alpha spherulites increases with crystallization temperature as well as the amount of PBS content. At 140A degrees C, spherulites in neat PVDF lose their ring banded feature, while coarse spherulites consisting of evident lamellar bundles could be found in 30/70 blend. |
