Cellulose acetate butyrate graphene oxide nanocomposite membrane: Fabrication, characterization, and performance

In this study, the effects of graphene oxide (GO) nanosheets on physicochemical properties and performances cellulose acetate butyrate (CAB) membranes were investigated. Nanocomposite fabricated using CAB a small amount GO in range 0 to 0.07 wt.%, conventional phase-inversion method. Membranes characterized by different methods their tested dead-end filtration system. Compared with pristine membrane, experimental results demonstrated an improvement features such as hydrophilicity, permeability, salt rejection, antifouling, stability. The proved increase porosity pore sizes addition. Furthermore, membrane containing wt.% exhibited low contact angle 37??and dramatic water flux about 450% (from 2 11 L/(m2 h)). Moreover, it rejection 39% for NaCl 87% Na2SO4, corresponding improvements 144 93%, respectively. revealed higher antifouling property 86% recovery stability terms performance thermal compared CAB.
