A sulfonated and nitrated polyether ether ketone/polyvinyl chloride modified atmosphere packaging delays the deterioration of grapes

Journal of the Science of Food and Agriculture
AbstractBACKGROUNDPolyether ether ketone (PEEK) was modified by a sulfuric and nitric acid mixed system to improve the solubility of the material and the gas selective permeability of the film. SN1 and SN5, synthesized from mixed acid systems (with ratios of nitric acid and sulfuric acid of 1:1 and 1:5, respectively) were chosen because they had ...

Comb-like solid polymer electrolyte based on polyethylene glycol-grafted sulfonated polyether ether ketone

Electrochimica Acta, 2017
Abstract Solid polymer electrolytes based on a novel comb-like copolymer, polyethylene glycol-grafted sulfonated polyether ether ketone (SPEEK- g -PEG), was designed and synthesized through the reaction between partially hydroxyl-functionalized sulfonated polyether ether ketone (SPEEK) and epoxy-functionalized PEG.

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.

Mild sulfonated polyether ketone ether ketone ketone incorporated polysulfone membranes for microbial fuel cell application

Journal of Applied Polymer Science, 2020
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.

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.

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 ...

Performances of Sulfonated Polyether Ether Ketone Composite Membranes for Fuel Cell Applications

International Journal of Nanoscience, 2015
A variety of modification approaches such as cross-linking and nano blending have been explored to prepare efficient membranes based on Sulfonated polyether ether ketone (SPEEK). The addition filler is also one of the most widely used approaches to modify the SPEEK.

Effect of sulfonation time on physicochemical, osteogenic, antibacterial properties and biocompatibility of carbon fiber reinforced polyether ether ketone

Journal of the Mechanical Behavior of Biomedical Materials, 2023
The carbon fiber reinforced polyetheretherketone (CFR-PEEK) has been increasingly used in orthopedics dentistry due to its excellent biocompatibility and mechanical properties. However, the biological inertness and poor antibacterial activity limit its clinical applications. This paper focused on the performances of CFR-PEEK with porous morphology that

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
