Effects of the carbon nanotube and polymer amounts on ultrafiltration membranes

Composite membranes with nano-sized inorganic materials have high selectivity, hydrophilicity, and improved fouling resistance. Blending Carbon Nanotubes (CNTs) in the polymer solution improves membrane properties like water permeability, The effect of amount, together CNT amount on properties, was investigated this work. There more than 10% increase hydrophilicity 1% addition, but it not altered amount. porosity increased almost 30% by addition prepared 12% concentration (P-10:C-0 P-12:C-0), only 16% occurred 15% (P-15:C-0). flux P-15:C-0 four times addition. Besides, resistance decreased increasing BSA rejection or solution. Hence a higher are prone to property improvements selectivity all different concentrations will life-time reduce treatment cost.
