| Abstract: | The modification of cellulose acetate by toluene diisocyanate to form cellulose acetate carbamate (CAC) for inproving its physical properties and microbial resistance was studied. The effects of reaction time and temperature, composition of reaction system, dosage of catalyst, and the kind of solvents used to isolate the product on the properties of the product CAC were investigated in detail. The membrane cast from CAC was tested in terms of salt rejiection, water, flux, resistance to hydrolyzation and microbial degradation. Results show that CAC is one of the excellent membrane materials with high salt rejection, good resistance to microbial degradation and hydrolyzation. |
