| 中文摘要 | the aim of this work is to investigate the effect of consecutive shear on the crystallization of an amorphous aromatic polyimide (pi) derived from 3,3',4,4'oxydiphthalic dianhydride (3,3',4,4'-odpa) and 4,4-oxydianiline (oda). at 260 degrees c, the increase of shear rate or shear time leads to the increase of crystallinity. indeed, increasing shear rate can also accelerate the crystallization behavior. moreover, it was found that a new melting peak appeared at higher temperature for long time or high rate sheared sample. the enhancement of crystallization behavior appears directly linked to the increase of crystal thickness. particularly, the effect of shear temperature was investigated, and the results revealed that the crystallization of the pi was more sensitive to shear at 260 degrees c, which was 10 degrees above the glass transition temperature (250 degrees c) of the pi. possible mechanism was proposed to illustrate the effect of consecutive shear on the crystallization of the pi polymer. |
