In this study, cellulose acetate (CA) and calcium oxide was used to manufacture an CA-CaO separator with enhanced stability and was coated on polypropylene (PP). The high melting point of CaO and the complexation of CaO with carbonyl groups in CA increased the stability. Since PP is known to have a higher mechanical stability than CA, the CA-CaO separator was coated on PP support, increasing the stability of the separator. Adhesion was imparted between the CA film and PP film without a separate adhesive due to the swelling effect of solvent and the water pressure treatment, and pores were even formed by the pressure. Water flux data showed that cellulose acetate containing CaO coated on polypropylene (CA-CaO on PP) obtained high flux value of 71.67 L/m2h (LMH) at a pressure of 8 bar. |
