In situ hybrid composites of thermoplastic poly(ether ether ketone), poly(ether sulfone) and polycarbonate

Composites Science and Technology, 2000
Abstract In order to overcome the poor processability of short-fibre-reinforced thermoplastics and to enhance the mechanical performance of thermoplastics reinforced with thermotropic liquid crystalline polymer (TLCP) fibrils (in situ composites), a new concept of an in situ hybrid composite has been put forward.

Study on the compatibility of the blend of poly(aryl ether ether ketone) with poly(aryl ether sulfone)

Journal of Applied Polymer Science, 1990
AbstractPoly(aryl ether ether ketone) is found to be compatible with poly(aryl ether sulfone) at a blending temperature 310°C. There is a single glass transition temperature (Tg) for various compositions of the blend. The relationship ofTgwith composition obeys Gordon‐Taylor's equation, where the adjustable parameter k is 0.43.

Crystallization and melting behavior of poly(ether ether ketone)/poly(aryl ether sulfone) blends

Journal of Applied Polymer Science, 2003
AbstractThe crystallization and melting behavior of poly(ether ether ketone) (PEEK) in blends with poly(aryl ether sulfone) (PES) prepared by melt mixing are investigated by differential scanning calorimetry (DSC) and wide‐angle X‐ray scattering (WAXS).

Dynamic mechanical behavior of poly(ether ether ketone)/poly(ether sulfone) block copolymers

Macromolecular Chemistry and Physics, 1996
AbstractPoly(ether ether ketone) (PEEK)/poly(ether sulfone) (PES) block copolymers were synthesized via condensation reaction between fluorine‐terminated PEEK oligomers and hydroxyl‐terminated PES oligomers. The dynamic mechanical behavior of a composite sample prepared by compression molding of a glass fibre cloth and the copolymer was investigated by

Poly(ether ether ketone)/poly(aryl ether sulfone) blends: Melt rheological behavior

Journal of Polymer Science Part B: Polymer Physics, 2004
AbstractDynamic rheological measurements were carried out on blends of poly(ether ether ketone) (PEEK)/poly(aryl ether sulfone) (PES) in the melt state in the oscillatory shear mode. The data were analyzed for the fundamental rheological behavior to yield insight into the microstructure of PEEK/PES blends.

Poly(vinylbenzyl sulfonic acid)-grafted poly(ether ether ketone) membranes

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2014
Abstract In this study, an aromatic hydrocarbon based polymer electrolyte membrane, poly(vinylbenzyl sulfonic acid)-grafted poly(ether ether ketone) (PEEK- g -PVBSA), has been prepared by the simultaneous irradiation grafting of vinylbenzyl chloride (VBC) monomer onto a PEEK film and subsequent sulfonation.

Sulfonated carbon nanotubes/sulfonated poly(ether sulfone ether ketone ketone) composites for polymer electrolyte membranes

Polymers for Advanced Technologies, 2011
AbstractA series of composite membranes consisting of sulfonated carbon nanotubes (sCNTs) and sulfonated poly(ether sulfone ether ketone ketone) were successfully fabricated via the solution casting method. The chemical structure, as well as the long‐term stability of the sCNTs in different solvents, was investigated by Fourier transform infrared (FTIR)

Studies on Proton Conductivity and Methanol Permeability of Poly(ether sulfone)/Sulfonated Poly(ether ether ketone) Blend Membranes

MRS Proceedings, 2008
AbstractPartially Sulfonated Poly(ether ether ketone) (SPEEK) samples were prepared by modification of corresponding poly(ether ether ketone) (PEEK) with concentrated sulfuric acid. Poly(ether sulfone)(PES) was blended into SPEEK to prepare PES/SPEEK blend membranes by solution casting.

Sulfonated poly(ether ether ketone) and sulfonated Poly(1,4-phenylene ether ether sulfone) membranes for vanadium redox flow battery

Nafion® is a currently used Proton Exchange Membrane (PEM) in Vanadium Redox Flow Batteries (VRB). It is an excellent proton conducting and fully hydrated membrane, but it has a very high cost. In order to reduce the cost of the membrane used in VRB and to reduce the vanadium permeability across the membrane during the operation, sulfonated poly (ether
