... conditions of a polyacrylonitrile (PAN) ultrafiltration membrane for wastewater treatment was investigated. The PAN membranes were prepared by the phase-inversion process in a water gelation bath using casting solutions of varying compositions of PAN/polyvinylpyrolidone (PVP)/N,N-dimethylacetamid ...

Effect of production conditions on morphology and permeability of asymmetric cellulose acetate membranes
... cellulose acetate (CA) (Mw = 52,000) was mixed with polyethylene glycol (PEG) (Mw = 400) as an additive in N-methyl-2-pyrrolidone as a solvent. The phase inversion method was used for preparation of flat sheet membranes. Effects of CA and PEG concentrations and also coagulation bath temperature o ...

Preparation and characterization of polyacrylonitrile-based membranes: Effects of internal coagulant on poly(acrylonitrileco-maleic acid) ultrafiltration hollow fiber membranes
Ultrafiltration hollow-fiber membranes (UHFMs) of poly(acrylonitrile-co-maleic acid) (PANCMA) were prepared by a dry-wet phase inversion process. The morphologies of inner surface and cross section for these hollow fibers were inspected with scanning electron microscopy. I ...

Trade-off between thermodynamic enhancement and kinetic hindrance during phase inversion in the preparation of polysulfone membranes
Polysulfone membranes were prepared via the diffusion-induced phase inversion process from casting solutions consisting of polysulfone, dimethyformamide, and polyvinyl pyrrolidone as a polymeric additive. The effec ...
