Development of graphene oxide-cellulose acetate nanocomposite reverse osmosis membrane for seawater desalination

Cellulose acetate (CA)/Graphene oxide (GO) nanocomposite membrane was prepared by phase inversion method. GO nanosheets were added to CA matrix with the aim of improving seawater desalination performance of asymmetric CA reverse osmosis (RO) membrane and enhancing mechanical and thermal stability. GO with grain size of 2.7 nm was synthesized through modified Hummer method and dispersed in CA matrix to prepare GO/CA nanocomposite membranes. The...
