Because the crystallization of CTFE segment of F2314, the additional absorption peaks observed at 580cm-1,506cm-1 and 438cm-1 of annealed F2314 samples by FTIR spectroscopy and it is in agreeing with the results from the WAXD measurement.

• 在等温处理时,由于F2413样品中CTFE链段结晶,FTIR在580cm-1,506cm-1及438cm-1出现PCTFE晶区的IR特征吸收峰,实验结果与WAXD测试结果一致。
