Phenolphthalein-based cardo poly(arylene ether sulfone): Preparation and application to separation membranes

Adsorption Properties of Thiol-Functionalized Silica Nanoparticles Prepared for Application in Poly(ether sulfone) Nanocomposite Membranes

Laser Light-Scattering Study of Novel Thermoplastics. 2. Phenolphthalein Poly(ether sulfone) (PES-C)

Five narrowly distributed fractions of phenolphthalein poly(ether sulfone) (PES-C) were studied in CHCl3 by both static and dynamic laser light scattering (LLS) at 25 °C. The dynamic LLS showed that the PES-C samples contain some large polymer clusters as in previously studied phenolphthalein poly(ether ketone) (PEK-C). These large clusters can be removed by a 0.1-ím filter. Our results showed ...

Tailoring the Characteristics of Poly (phenylene-ether-ether) sulfone Membrane for Efficient Glycerol/Biodiesel Separation

Poly (phenylene-ether-ether) sulfone membrane was fabricated and characterized by efficient glycerol/biodiesel separation produced from waste cooking oils trans-esterification. The membrane preparation was processed by phase inversion technique. The morphology, Physico-chemical properties and separation behavior of membranes were studied at various PPEES concentration. A uniform surface was...

A novel guanidinium grafted poly(aryl ether sulfone) for high-performance hydroxide exchange membranes.

A novel poly(aryl ether sulfone) ionomer containing hexaalkylguanidinium groups was synthesized, and membranes formed from this polymer displayed large ionic clusters, high hydroxide conductivity, and excellent solubility in low boiling point water-soluble solvents such as ethanol and methanol.

Porous Nanocomposites with Integrated Internal Domains: Application to Separation Membranes

Asymmetric membranes with layered structure have made significant achievements due to their balanced properties and multi-functionalities that come from a combination of multiple layers. However, issues such as delamination and substructure resistance are generated by the intrinsic layered structure. Here, we present a strategy to integrate the traditional layered structure into an asymmetric b...
