The Crystallization of Poly (3-dodecylthiophene) in an Oriented Solidification Environment
摘要:
The crystallization behaviors of poly (3-dodecylthiophene) (P3DDT) under two different oriented solidification conditions, i.e., two different relative relations (90° and 180°) between the directions of gravity and solidification, were investigated. X-ray diffraction results reveal that although similar layered structures are formed, under the condition of the relative relation 180°, temperature gradient has greater effects on the perfect degree of the layered structures of P3DDT. It also can be concluded that after recrystallization, the layered structures of P3DDT can be improved at relative relation 90°, but the orderly degree of the arrangements of alkyl side chains are not improved yet, even is reduced for both of the oriented solidification conditions.
