In this study, an eco-friendly and inexpensive cellulose acetate separator was fabricated and a method of preparing stable polymer by combining a polypropylene film and cellulose was proposed. The cellulose acetate solution was coated on the polypropylene film with a doctor blade and water-pressure was applied to the bonded polymers to generate the interconnected pores and completely bond the cellulose acetate onto the polypropylene. In addition, lactic acid was added to cellulose acetate to induce a plasticizing effect for abundant pore formation. The binding was confirmed using FT-IR and SEM, and the pore size generated from the cellulose acetate side was found to be less than 1 μm on average. TGA was used to measure the thermal stability of the connected polymers.
