Abstract: In this paper, melt crystallization of poly(ether ether ketone ketone)(PEEKK) under strong electric field was investigated. In the crystal structure of PEEKK, the length of c axis was found to be 1.075 nm, increasing by 7% compared to that of PEEKKcrystallized without strong electric field. The molecule chains might take a more extended conformation through the opening of the bridge bond angles by increasing from 124° to 144° under strong electric field in the crystal structure.

Key words: PEEKK, Electric field, Crystallization, Crystal structure
