Evaluation of process parameters for poly(ether ether ketone) to poly(ether ether ketone) friction welded joint

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2021
Poly(ether ether ketone) is a semicrystalline organic polymer. It has widely been used as high-performance engineering plastic owing to its high melting point (343 °C), excellent mechanical strength, and outstanding chemical resistance. Therefore, poly(ether ether ketone) and its composites have shown lots of applications in aerospace and medical ...

Thermoreversible Gelation of Poly(ether ether ketone)

ACS Macro Letters, 2017
Solutions of poly(ether ether ketone) in dichloroacetic acid have been shown to form monolithic, thermoreversible gels at temperatures ranging from 10 to 140 °C. A phase diagram was constructed over broad concentration and temperature ranges, and the phase boundary suggests an upper critical solution temperature (UCST) behavior. Furthermore, poly(ether

Anomalous diffusion in poly-ether-ether-ketone

Chemical Engineering Science, 1994
Poly-ether-ether-ketone (PEEK) is a thermoplastic tough polymer used as a matrix for advanced composite materials in aeronautic applications. The investigation of its resistance to humid environment and to exposure to organic and chlorinated solvents is extremely important.

Synthesis and structural properties of sulfonated poly ether ether ketone (SPEEK) and Poly ether ether ketone (PEEK)

AIP Conference Proceedings, 2020
Polyether ether ketone (PEEK) is one of the most important aromatic polymers; it has many applications in nanotechnology. The new sulfonated polyether ether ketone (sPEEK) membrane was successfully prepared, by using sulfonation processed for PEEK polymer; 10 grams of PEEK sample were dissolved progressively in 200 ml of sulfuric acid (H2SO4).

Processable poly(ether ether ketone imide)s

High Performance Polymers, 2021
New aromatic poly(ether ether ketone imide)s, [PEEKimide]s, were synthesized successfully from 1,3-bis-4′-(4″-aminophenoxy benzoyl) benzene and various commercially available aromatic dianhydrides, such as pyromellitic dianhydride (PMDA), 3,3′,4,4′-benzophenone tetracarboxylic dianhydride (BTDA), 3,3′,4,4′-biphenyl tetracarboxylic dianhydride (BPDA ...

Trifluoromethylated poly(ether ether ketone)s

Polymer, 1994
Abstract Novel copolymers of poly(ether ether ketone) containing ring trifluoromethyl groups have been synthesized by starting with trifluorobenzophenone monomers. Unlike poly(ether sulfone) analogues, it is possible to prepare copolymers which contain CF 3 groups ortho to the ether bridges.

Rheological properties of phenophthalein poly(ether ether ketone)

Polymer Engineering & Science, 1996
AbstractThe rheological properties of the novel engineering thermoplastic phenophthalein poly(ether ether ketone) (PEK‐C) have been investigated using both a rotational and a capillary rheometer. The dependence of the viscosity on the shear rate and temperature was obtained.
