Cross-flow deposited hydroxyethyl cellulose (HEC)/polypropylene (PP) thin-film composite membrane for aqueous and non-aqueous nanofiltration

•TFC membrane with HEC barrier layer and PP support was designed for nanofiltration.•Membranes were fabricated via cross-flow deposition followed with cross-linking.•Improved adhesion between HEC layer and PP porous substrate was achieved.•Membrane fabrication was free of organic solvent and possessed good reproducibility.•Membrane exhibited good perm-selectivity, chemical stability and solvent resistance.
