Mechano-optical Behaviour of Amorphous PEEK Films: Role of Relaxation and Retraction
Poly (ether ether ketone) (PEEK) is a linear aromatic high performance thermoplastics. It is regarded as the highest performance material capable of being processed on conventional thermoplastic equipment. Level of crystallinity and microsturucture can be optimized through post process thermal teatment involving melt orientation and relaxation. Birefringence as an overall measure of optical anisotropy of polymeric materials provides insight into the structural organizations, particularly when it is coupled with true stress and strain measurements. In this study, an integrated on-line mechano-optical measurement system developed at the University Akrons Institute of Polymer Engineering was used to study the transient processes that take place during post processing of PEEK films following biaxial deformation. The mechano-optical studies were augmented with off-line structural measurement techniques in an attempt to control the final properties of thin PEEK films.
