A Fourier transform Raman spectroscopy study of poly (ether ether ketone)/polytetrafluoroethylene (PEEK/PTFE) blends

A study of blends consisting of the polymers poly (ether ether ketone) (PEEK) and polytetrafluoroethylene (PTFE) using Fourier transform Raman spectroscopy is described. The data presented show that the presence of PTFE in the PEEK environment causes the PEEK molecules to become more ordered. The most significant changes to the PEEK molecules are shown to occur with only small additions of PTFE. These observations are compared with reported frictional and hardness data.
