Surface modification and performance enhancement of nano-hybrid f-MWCNT/PVP90/PES hemodialysis membranes

Overview of PES biocompatible/hemodialysis membranes: PES–blood interactions and modification techniques

“…[108] synthesized acid functionalized multiwall carbon nanotubes and PVP nanocomposites and blend them with PES polymer. They reported that these nanocomposites increased the clearance ratio of urea, creatinine and lysozyme (56.3%, 55.08% and 28.40%) respectively as depicted in Fig.…”

Improved Performance of CaCl 2 Incorporated Polyethersulfone Ultrafiltration Membranes

“…The casting dope for each membrane consisted of fixed amount of PES and PVP while the concentration of CaCl 2 was varied in regard to the DMF solvent, as shown in Table 1. Based on previously reported works, it was understood that the optimum concentration of PES and PVP for good miscibility and polymer interaction was 18 wt% and 2.5 wt% respectively [39,46]. Hence the PES and PVP concentration were fixed to 18 wt% and 2.5 wt% while the concentration of CaCl 2 was varied from 0 wt% to 3 wt%.…”

Composite Hybrid Membrane Materials for Artificial Organs

“…Irfan et al [38] synthesized a composite polysulfonepolyvinylpyrrolidone-carbon nanotube membrane to filter urea, creatinine, and lysozyme. Carbon nanotubes have been treated with a mixture of sulfuric acid and nitric acid to generate -COOH and respective -OH groups on the surface and subsequently were bonded to polyvinylpyrrolidone (PVP).…”
