Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
A new type of organic and inorganic cation exchange membranes was prepared based on poly(vinylidene fluoride) modified by SiO2 nano-sized particles via blending process in order to obtain better membranes permselectivity of ions in electrolyte with high concentration and better membranes antifouling performance. The membrane transport parameters were investigated in terms of membrane water content, ion exchange capacity (IEC) and membrane conductivity, permselectivity. The results that water uptake and contact angle of these membranes indicated that these membranes have better hydrophilic than PVDF membranes. It was found that membranes conductivity and permselectivity increased with increasing silica content. With 0.28% of SiO2 content and at 0.055mol/L of mean electrolyte solution, permselectivity of Na+ was 0.96. These cation exchange membranes with better membrane conductivity, ion permselectivity may be used for application in water treatment process and fuel cell.
