Crystallization behaviour of poly(ether-ether-ketone)

Polymer, 1986
Abstract A study has been made of the crystallization behaviour of poly(ether-ether-ketone), PEEK, under isothermal and non-isothermal conditions. A differential scanning calorimeter was used to monitor the energetics of the crystallization process from the melt and from the rubbery amorphous state.

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 ...
