Preparation and characterization of nanocellulose acetate and acrylate polymer composite membrane

Abstract

In the present study, a nanocellulose acetate and acrylate polymer composite membrane was formed by the phase transfer technique. The physical and mechanical properties, water flux, and desalination performance of the achieved composite membrane were investigated. When 3 % (w/w) acrylate polymer, 10 % acetylated nanocellulose, and 0.3 % mass fraction of TiO2 were used for the formation of the membrane, the obtained product could reach a tensile strength of 1.97 N/mm2 and a pure water flux of 51 L/(m2 h). Moreover, the composite membrane achieved a desalination rate of 92.4 %. Thus, the obtained composite membrane could meet the performance requirements for the treatment of industrial wastewater.
