Antibacterial Properties of Polysulfone Membranes Blended with Arabic Gum

Hydrodynamic Properties of Whole Arabic Gum

The most economically important of the hydrodynamic properties of a material are viscosity and density, which allow determining the intrinsic viscosity of raw materials used in the food industry. They serve as an indirect measure of molecular weight (M), hydrodynamic radius (RH), number of Simha, (ν(P)), Perrin parameter (P); hydration value (δ), Scheraga-Mandelkern parameter (β), and Flory par...

Enhancing the Compatibility, Hydrophilicity and Mechanical Properties of Polysulfone Ultrafiltration Membranes with Lignocellulose Nanofibrils

Lignocellulose nanofibrils (LCN) and cellulose nanofibrils (CNF) are popular nanometer additives to improve mechanical properties and hydrophilic abilities; moreover, lignocellulose has potential as a natural adhesion promoter in fiber-reinforced composites. LCN and CNF were blended into polysulfone (PSF) to prepare ultrafiltration membranes via the phase inversion method. These additives were ...

Nafion-layered sulfonated polysulfone fuel cell membranes

Sulfonated polysulfone (SPSU) with high ion exchange capacity (IEC) and ion conductivity was synthesized through deep sulfonation of polysulfone using the trimethysilyl chlorosulfonate as sulfonation agent. The silicon-containing compounds formed during the synthesis of SPSU were completely removed from the SPSU by simple evaporation. Water swelling, ion exchange capacity, conductivity and fuel...

Advances in Polysulfone-Based Membranes for Hemodialysis

The polysulfone-based membrane has been used in hemodialysis (HD) and it is continuously developed to maintain its sustainability on the subject of biocompatibility. During the polysulfone-based membrane development, several parameters should be considered to improve the membrane performances, such as excellent biocompatibility, appropriate ultrafiltration rate, and effective clearance of the t...
