Thin film FO membrane with LDH-NPs blended PSf substrate was fabricated.
The addition of LDH-NPs endowed the PSf substrate with increased properties.
The water flux was increased from 12.7 to 18.1 L m−2 h−1 by the addition of LDH-NPs.
This contribution represents the first application of LDH-NPs in FO membranes.
