International need for water quality is placing a high demand on separation technology to develop advanced oxidative processes polyethersulfone (PES) membranes help improve purification. Therefore, VUV photo-oxidation with low pressure Ar plasma was studied the hydrophilicity of PES by flowing oxygen over surface during treatment. X-ray photoelectron spectroscopy (XPS) detected decrease in C at...

Metal nanoparticles are known as highly effective catalysts although their immobilization on solid supports is frequently required to prevent aggregation and to facilitate the catalyst application, recovery, and reuse. This paper reports the intermatrix synthesis of Pd0 nanoparticles in sulfonated polyethersulfone with Cardo group membranes and their use as nanocomposite catalytic membrane reac...

The polymerization-induced phase-separation process of polyethersulfone (PES)-modified epoxy systems was monitored in situ continuously on a single sample throughout the entire curing process by using optical microscopes, time-resolved light scattering (TRLS), scanning electronic microscopes (SEM), and a rheometry instrument. At specific PES content a viscoelastic transformation process of phas...
