Polyetheretherketone (PEEK) is a semicrystalline polyether prepared under milder conditions via aromatic nucleophilic substitution reaction of the potassium salt of hydroquinone and 4,4′-difluorobenzophenone as shown in Figure 2.27.Several companies conducted early work on PEEK, which resulted in low molecular weight polymer, owning to crystallization and precipitation from solution.

Ultra‐low coefficient of thermal expansion (CTE) is an elusive property, and narrow temperature ranges of operation and poor mechanical properties limit the use of conventional materials with low CTE. We structured a periodic micro‐array of bi‐metallic cells to demonstrate ultra‐low effective CTE with a wide temperature range. These engineered tunable CTE thin film can be applied to ...

Characterization of thermally aged polyetheretherketone fibres

They found that the coefficient of thermal expansion for PEEK could be reduced to values similar to that of the copper metalization, by using the talc filler at 30 wt.%. In addition, as an alternative substrate for FPC to PI, PEEK offers similar thermal stability to PI, with superior chemical stability (against alkaline media) and substantially lower water absorption than PI.

The thermal expansion coefficient of Ti is 8.6 × 10 − 6 /°C, which is much lower than that of PEEK (4.7 × 10 − 5 /°C) , . During the hydrothermal treatment, the difference in the thermal expansion coefficients should lead to the deterioration of adhesion of the Ti intermediate layer to the PEEK substrate due to a tensile stress generation in the Ti layer. But the thin Ti layer may more ...
