... 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 ...
Desalination 144 (2002)

PVDF hollow fiber membranes were prepared from commercially available polyvinylidenefluoride and N,N-dimethylacetamide (DMAc) by the dry-jet wet phase inversion process. Lithium chloride and water were used as additives. Mean pores size and effective surface porosity were evaluated by the ga ...

... 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 ...

Capsules of PEEKWC are prepared using a membrane process combined with phase inversion technique. Polymeric droplets were prepared using a mono-pore film in polyethylene with pore diameter ranging from 300 to 1000 mm. Th ...
Desalination 199 (2006)

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 ...
Desalination 159 (2003)

Bisphenol A (BPA)-imprinted polysulfone (PSf) particles for the binding and recognition of BPA were prepared by means of a phase inversion technique. The porosity of the PSf particles was about 70%. Binding and recognition of BPA for the particles were investigated; th ...
