我想知道，会不会有很多末端基团(end group) to be trapped in crystalline region?
大家见过关于这方面问题的文章? |

还有中间相
region?
末端基团占的比例不会很多吧，对性能的影响不会太大吧

and accumulated on the crystal surface because it will affect the stability of
crystals. But in some extreme case like low temp, which leads to fast
kinetics, the end group or some other defects can be trapped into the
crystalline phase. In that case, kinetics plays more important role than
thermodynamics. Those trapped defects may still have chance to be excluded
through annealing at higher temperature.

this.
I agree with you opinions which make lots of sense. I need some relevent
references to describe these ideas.I cannot find some. Can you recommend some
relevant papers, especially some reviews.Thanks a lots.

发帖数: 115 | 6 我认为关于共晶，kinetics 是一个很重要的影响因数
但是最重要的不仅仅是这个
最更根本的是取决defect的defect energy
