Anaphylactic reaction induced by a polysulfone/polyvinylpyrrolidone membrane in the 10th session of hemodialysis with the same dialyzer
(WILEY-BLACKWELL, 2011)
The majority of severe hypersensitivity reactions in hemodialysis patients have occurred due to sensitization to ethylene oxide or to nonbiocompatible membrane dialyzers. The use of polysulfone dialyzers rarely causes ...
Properties and structure of cyanate ester/polysulfone/organoclay nanocomposites
(Elsevier, 2006-05)
In this paper, a cyanate ester (CE) matrix has been modified with polysulfone and an organic montmorillonite (Nanofil 919). The blend was thermally cured in presence of copper acetylcetonate and nonylphenol. The morphology ...
Phase separation in polysulfone-modified epoxy mixtures: Relationships between curing conditions, morphology and ultimate behavior
(Elsevier, 1999-10-29)
Chemorheology of curing as well as the phase separation behavior of polysulfone (PSU)-modified diaminodiphenylmethane-cureddiglycidylether of bisphenol-A epoxy mixtures have been studied using several techniques. The delay ...
Synthesis Polysulfone-Acetylethanol Ultrafiltration Membranes. Application to Oily Wastewater Treatment
(Science and Education Publishing, 2013-09)
Chemical functionalization of polymers after the synthesis of membranes has great importance for various applications separative processes of industrial or environmental interest. Polysulfone (PSf) is one of the most applied ...
Montmorillonite as a component of polysulfone nanocomposite membranes
(ELSEVIER SCIENCE BV, 2010)
Nanocomposite membranes containing polysulfone (PSI) and sodium montmorillonite from Wyoming (MMT) were prepared by a combination of solution dispersion and the immersion step of the wet-phase inversion method. The purpose ...
Asymmetric polysulfone and polyethersulfone membranes: effects of thermodynamic conditions during formation on their performance
(Elsevier Science BvAmsterdamHolanda, 2000)
Morphology profiles obtained by reaction-induced phase separation in epoxy/polysulfone/poly(ether imide) systems
(Wiley, 2005-02-15)
The reaction-induced phase separation in epoxy/aromatic diamine formulations simultaneously modified with two immiscible thermoplastics (TPs), poly(ether imide) (PEI) and polysulfone (PSF), has been studied. The epoxy ...
A high selectivity quaternized polysulfone membrane for alkaline direct methanol fuel cells
(Elsevier Science, 2015-02)
Alkaline membranes based on quaternized poly(arylene ether sulfone) (QPAES) were characterized in relation to their water and methanol uptake, methanol permeability, electrical conductivity, and mechanicalproperties. The ...
Electromagnetic characterization of recyclable polymer nanofibers based on PSU/carbonyl iron
(2019-01-01)
This study investigated and defined the optimal processing parameters for the electrospinning of polysulfone polymer solutions with N,N-dimethylacetamide. Variation of parameters such as solute concentration, electrical ...
