| 中文摘要 | a new crystal modification induced by strain and denoted as form ii exists alongside the dominant form i structure in the uniaxially oriented poly(ether ether ketone) (peek) and the related polymers. the crystal structure of form ii for peek is also found to possess a two-chain orthorhombic packing with unit cell parameters of a equal to 0.475 nm, b equal to 1.060 nm, and c equal to 1.086 nm. more extended and flattened chain conformation of form ii relative to that of form i is expected to account for an 8% increase in c-axis dimension, which is attributed to the extensional deformation fixed in situ through strain-induced crystallization during uniaxial drawing. annealing experiments suggest that form ii is thermodynamically metastable and can be transformed into more stable form i by chain relaxation and reorganization at elevated temperature without external tension. this strain-induced polymorphism exists universally in the poly(aryl ether ketone) family.
