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 ...

Composite membrane of sulfonated polyether ether ketone (sPEEK) – Chitosan for direct methanol fuel cell

AIP Conference Proceedings, 2020
The challenge of commercialization of fuel cells in Indonesia is mainly the caused by high manufacturing costs, particulary the cost of electrolyte membrane which is one of the important components of fuel cells. The use of inexpensive and abundant local materials such as sulfonated polyether ether ketone polymers and chitosan, to replace the currently

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,

Scaleup suitability of sulfonated polyether ether ketone membrane‐based microbial fuel cell

Environmental Progress & Sustainable Energy, 2015
A sustainable clean energy production from oxidation of biodegradable materials was carried out in a microbial fuel cell (MFC) stack consisting of four MFC units. The stack was fabricated and tested for its scalability using a high engineering, low oxygen mass transfer membrane; namely, sulfonated poly ether ether ketone. Sodium acetate was used as the

Influence of sulfonated SiO2 in sulfonated polyether ether ketone nanocomposite membrane in microbial fuel cell

Fuel, 2015
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.
