In this work, novel thin film composite membranes (TFCs) of poly (ether-6-block amide) (Pebax-1657) on a polyvinyl chloride (PVC) ultrafiltration membrane as support were prepared using inclined coating method for CO2 separation. Investigating the effects of top selective layer thickness formed by controlling the coating angle (15-60°) and polymer solution concentration (5-10 wt.%), ...

In this study, Poly (L-lactic acid)/Captopril composite nanofiber membranes were electrospun for drug delivery. Different mass fractions of Poly (L-lactic acid), different ratios of Captopril and the influences of PEG4000 added in the spinning solution are discussed. The morphology, chemical components, the surface areas and pore sizes, wettability of the composite nanofiber membranes were inve...

Sandwich-structured composite zeolite membranes with enhanced hydrogen selectivity were prepared on porous α-Al(2)O(3) supports by using 3-aminopropyltriethoxysilane as an interlayer.

?2 microglobulin (?2m) fibril has been recognized as the major factor of dialysis-related amyloidosis. elevated serum levels are thought to be the basis for tissue deposition. in order to evaluate the effect of cellulosis membrane (fb 110) and treatment duration on s?2m levels, we determined serum levels in 23 hemodialyzed patients with end-stage renal failure. s?2m levels were markedly elevate...

In this paper, polydimethylsiloxane (PDMS) composite membranes that were supported using polyvinylidene fluoride (PVDF) microfiltration membrane were developed for the pervaporation (PV) of dimethyl carbonate (DMC) from a methanol solution. Experimental studies on the solubility and the diffusivity of pure DMC and methanol in the membrane were first measured. Higher DMC uptake indicates that th...

In this work, ceramic hollow fiber supported polydimethylsiloxane (PDMS) composite membranes were developed by dip-coating PDMS layer on the surface of macroporous ceramic hollow fiber support. By controlling the properties of polymer solution and ceramic hollow fiber, high-quality ceramic hollow fiber supported PDMS composite membranes were fabricated for pervaporation (PV) recovery of biobuta...

Barrier membranes are used in periodontal applications with the aim of supporting periodontal regeneration by physically blocking migration of epithelial cells. The present work proposes a combination of chitosan (CHT) with bioactive glass nanoparticles (BG-NPs) in order to produce a novel guided tissue and bone regeneration membrane, fabricated by solvent casting. The CHT/BG-NP nanocomposite m...

The effect of typical membrane processing conditions on the structure, interfacial morphology, and gas separation performance of MOF/polymer nanocomposite membranes is investigated. In particular, the ZIF...
