| dc.description.abstract | Blend polysulfone (PSF)/cellulose acetate (CA) membranes have prepared by phase inversion
method. In here, CA was prepared from bacterial cellulose by acetylation reaction. Various
temperature of coagulation bath were used as variable to investigated water uptake, water flux,
porosity and thermal properties of membranes. As comparison, the CA commercial (CCA) was
also investigated with the same parameters. As the result, the functional group analysis by FTIR
show that CA has successfully prepared from bacterial cellulose. The parameters include water
uptake, water flux and porosity have the similar trend. The parameters increase with increasing of
temperature of coagulation bath. The other hand, CCA membrane have similar trend to CA
membranes for parameter of water water uptake, water flux and porosity. However, CCA
membrane is higher than CA membranes for all parameters. Thermal analysis by Differential
Scanning (DSC) showed that all blend membranes with different temperature of coagulation bath
have single transition glass temperature (Tg) that indicated that molecular homogeneity. | en_US |
