Effect of Physical Aging on the Properties of Films of Amorphous Poly(Ether Ether Ketone) (Peek)
Physical aging of films of poly(ether ether ketone) kept for 2 months at 120 degrees C was studied. The extent of aging was evaluated with different techniques. Aged samples show different thermal behavior and exhibit different mechanical, transport, and viscoelastic properties. An attempt was made to establish the accuracy of different techniques and their reliability in detecting the extent of physical aging.
