Polysulfone — sulfonated poly(ether ether) ketone blend.
One of the most common methods is nucleophilic substitution of an aromatic chloro- or fluorosulfone by a phenoxide ion. For example, the reaction of the disodium salt of bisphenol A with dichlorodiphenyl sulfone yields Bisphenol A polysulfone (PSU): COMMERCIAL Polysulfones.
Characterization of Polysulfone Membranes Prepared with Thermally Induced Phase Separation Technique.. interconnected sponge-like and highly permeable polyvinylidene fluoride hollow fiber membranes for direct contact membrane distillation (Tianjin, China: European Polymer Journal) 262-272.
Nanostructured polysulfone composite membranes 41 composite membrane was kept into a persulfate acid solution for 24 hours. The obtained membranes were stored in water: methanol mixture (1:1). Membranes characterization. Membrane samples (4.8, 5.2, and 9.0 cm diameter disks) were characterized by Fourrier transformed infrared spectroscopy.
Polymeric membrane is a proven technology for water purification and wastewater treatment. The membrane is also commercialized for gas separation, mainly for carbon dioxide removal and hydrogen recovery. Characterization techniques are excellent tools for exploring the membrane structure and the chemical properties. This information can be then optimized to improve the membrane for better.
Preparation and characterization of a polysulfone ultrafiltration membrane for bovine serum albumin separation: Effect of polymer concentration.
Polysulfone allows easy manufacturing of membranes, with reproducible properties and controllable size of pores down to 40 nanometers. Such membranes can be used in applications like hemodialysis, waste water recovery, food and beverage processing, and gas separation. These polymers are also used in the automotive and electronic industries.
Surface Characterization of Biocompatible Polysulfone Membranes Modified. with hydrophilic and hydrophobic block entrapped to polysulfone membrane surface were investigated in terms of the degree of hydrophilicity. The asymmetric membrane was formed by phase inversion. Polysulfone (PSf, average Mw 30,000) (Udel P3500) supplied.
