Effect of type of solvent and non-solvents on morphology and performance of polysulfone and polyethersulfone ultrafiltration membranes for milk concentration
Effect of type of solvent and non-solvents on morphology and performance of polysulfone and polyethersulfone ultrafiltration membranes for milk concentration
- Polymers for advanced technologies, 16(10), p.717-724, 2005 .
Polysulfone (PS)and polyethersulfone (PES)ultrafiltration membranes were manufactured from a casting solution of the polymer, polyvinylpyrrolidone (PVP)in various solvents [N,N-dimethylacetamide (DMAc), N,N-dimethylformamide (DMF)and 1-methyl-2-pyrrolidone (NMP)] by immersing the prepared films in different non-solvents [water, 2-butanol, mixture of water and 2-butanol, mixture of water and 2-propanol (IPA)and mixture of water and 1-butanol].
