The synthesis of sulfonated polyethersulfone (SPES) and the

WebCS/SPES-PES composite membrane was prepared by coating the chitosan (CS) active layer onto the sulfonated polyethersulfone (SPES)-polyethersulfone (PES) support layer. The SPES-PES support layer was prepared by blending with hydrophilic SPES into PES matrix in a wet phase inversion process. X-ray photoelectron spectroscopy (XPS) characterization … Recently, sulfonated polyethersulfones (SPES) have been studied as a promising material candidate among many other aromatic hydrocarbon-based polymers for highly durable proton-exchange membranes in fuel cells. Several reviews have reported progress on durability from many reports on this work. See more Polysulfones are a family of high performance thermoplastics. These polymers are known for their toughness and stability at high temperatures. Technically used polysulfones contain an aryl See more Historical The simplest polysulfone poly(phenylene sulfone), known as early as 1960, is produced in a See more Polysulfone has one of the highest service temperatures among all melt-processable thermoplastics. Its resistance to high temperatures gives it a role of a flame retardant, without compromising its strength that usually results from addition of flame retardants. … See more The term "polysulfone" is normally used for polyarylethersulfones (PAES), since only aromatic polysulfones are used commercially. Furthermore, since ether groups are always … See more Polysulfones are rigid, high-strength and transparent. They are also characterized by high strength and stiffness, retaining these properties between −100 °C and 150 °C. The glass transition temperature of polysulfones is between 190 and 230 °C.
