An overview on the progress and development of modified sulfonated polyether ether ketone membranes for vanadium redox flow battery applications

High Performance Polymers, 2021
Vanadium redox flow batteries (VRFB) are among the most promising approaches to efficiently store renewable energies. In such battery type, Nafion is commonly used as membrane material but suffers from high vanadium crossover and cost.

Characterization and In Vitro Studies of Sulfonated Polyether Ether Ketone/Polyether Sulfone/Nano Hydroxyapatite Composite

International Journal of Polymeric Materials and Polymeric Biomaterials, 2014
Sulfonated polyether ether ketone (SPEEK)/polyether sulfone (PES)/nano hydroxyapatite (nHAP) composites were prepared with different nHAP filler concentrations. FTIR analysis confirmed the blend formation between SPEEK and PES. Surface morphology pictures showed agglomeration of the nHAP particles at higher percentage of loading.

Water recovery from flue gas using polyether block amide 2533/sulfonated poly(ether ether ketone) composite membrane

Journal of Applied Polymer Science, 2021
AbstractRecycling water from flue gas of coal‐fired power plants is of great significance to save energy and water resources and reduce environmental pollution. In the present work, two potential polymers (polyether block amide 2533(PEBAX 2533) and sulfonated poly(ether ether ketone) (SPEEK)) were investigated and showed high water vapor permeability ...

Proton conducting composite membranes from sulfonated polyether ether ketone and SiO2

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2009
Proton conducting composite membranes from sulfonated polyether ether ketone and SiO2 for direct methanol fuel cell (DMFC) application were prepared with sulfonated polyether ether ketone(SPEEK) and tetracethoxy silane(TEOS) by sol-gel method. The covalent crosslinking structure was formed between —SO3H of SPEEK via SiO2.

Diglycidyl ether of bisphenol-A epoxy resin–polyether sulfone/polyether sulfone ether ketone blends: phase morphology, fracture toughness and thermo-mechanical properties

Colloid and Polymer Science, 2006
The properties of diglycidyl ether of bisphenol-A epoxy resin toughened with poly(ether sulfone ether ketone) (PESEK) and poly(ether sulfone) (PES) polymers were investigated. PESEK was synthesised by the nucleophilic substitution reaction of 4,4’-difluorobenzophenone with dihydroxydiphenylsulfone using sulfolane as solvent and potassium carbonate as ...

Highly Sulfonated Poly(Ether Ether Ketone) Blend with Hydrophobic Polyether Sulfone as an Alternative Electrolyte for Proton Exchange Membrane Fuel Cell

Arabian Journal for Science and Engineering, 2020
Highly sulfonated poly(ether ether ketone) (sPEEK) offers high proton conductivity but lacks in mechanical stability due to poor swelling degree. Therefore, a promising approach has been introduced in this study by incorporating the hydrophobic polyether sulfone (PES) into sPEEK matrix. The effect of incorporating PES at various composition contents (5,

Nanocomposite membrane by incorporating graphene oxide in sulfonated polyether ether ketone for direct methanol fuel cell

Materials Today: Proceedings, 2021
Abstract Few-layers graphene oxide enriched with oxygen functional groups is successfully obtained and incorporated into sulfonated polyether ether ketone (SPEEK) matrix. The functional groups and the surface modification of membranes were identified using FTIR spectroscopy, and X-ray Photoelectron Spectroscopy (XPS). Subsequently, FESEM was employed
