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,

Sulfonated polyether ether ketone based composite polymer electrolyte membranes
Catalysis Today, 2001Electrochemical properties of a series of composite membranes prepared by incorporation of boron phosphate into polymeric matrix of sulfonated PEEK were studied. The conductivity of the composites was found to exceed largely that of pure SPEEK polymer. It was however lower than predicted by the effective medium theory for these mixtures.

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.

AbstractTo address the impediments of low power generation of Nafion, which is the main hurdle in the commercialization of microbial fuel cells (MFC), the current study focuses on developing a new PEM for MFC from mild sulfonation of PEKEKK with relatively improved physiochemical properties.

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

Abstract Microbial fuel cell (MFC) is a bioreactor for simultaneous electricity generation and wastewater treatment. Modified nanocomposite membranes based on sulfonated poly ether ether ketone (SPEEK) and sulfonated SiO2 (SiO2–SO3H) were fabricated and evaluated in a microbial fuel cell configuration.

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 ...
