▎ 摘　　要

NOVELTY - A forward osmosis thin-film composite membrane comprises a polymer support layer, an intermediate support layer comprising polydopamine and graphene oxide formed on the support layer and a polymer active layer formed on the intermediate support layer. The intermediate support layer has thickness of 10-500 nm. The amount of the graphene oxide is 0.5-20 wt.% with respect to amount of polydopamine. USE - Forward osmosis thin-film composite membrane is used for water-treatment module and water treatment system (all claimed) for water treatment and desalination. ADVANTAGE - The forward osmosis thin-film composite membrane has improved water permeability, excellent mechanical strength, durability, stain resistance, thermal stability and chemical stability, and reduced thickness, and can be cleaned by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of forward osmosis thin-film composite membrane.
