Spin\u2011spray\u2011assisted layer\u2011by\u2011layer (LbL) assembly is an innovative technique for producing nanostructured thin films due to its rapid deposition and excellent substrate coverage. In this article, Farid Fadhillah fabricated a nanofiltration (NF) membrane composed of multilayers of polyethyleneimine (PEI) and poly(sodium\u20114\u2011styrene sulfonate) (PSS) on a polysulfone (PSF) support. The resulting membrane was subsequently coated with a metal\u2013organic framework (MOF303).
\nThe fabricated (PEI\/PSS)\u2085\u2013MOF303 membrane demonstrated a rejection rate of 18.94 \u00b1 1.58% and a permeability of 0.91 \u00b1 0.13 L\/(h\u00b7bar\u00b7m\u00b2), while also exhibiting improved antifouling performance. These findings highlight the potential of spin\u2011spray\u2011assisted LbL assembly as a promising route for thin\u2011film composite membrane fabrication.
\nSurface characterization was performed using a commercially available AFM system equipped with a NanoWorld Arrow\u2011CONTR AFM probe<\/a>, a silicon cantilever with a force constant of 0.2 N\/m, operated in contact mode. Lateral images were used to visualize surface inhomogeneities across the scanned region. The NanoWorld AFM probe<\/a> ensured stable tip\u2013sample interaction, enabling high\u2011quality topographical and lateral force mapping. This article emphasizes the importance of selecting a reliable AFM probe for nanoscale membrane characterization.<\/p>\n
