Spin‑spray‑assisted layer‑by‑layer (LbL) meeting is an modern method for producing nanostructured skinny movies on account of its speedy deposition and wonderful substrate protection. On this article, Farid Fadhillah fabricated a nanofiltration (NF) membrane composed of multilayers of polyethyleneimine (PEI) and poly(sodium‑4‑styrene sulfonate) (PSS) on a polysulfone (PSF) help. The ensuing membrane was subsequently coated with a steel–natural framework (MOF303).
The fabricated (PEI/PSS)₅–MOF303 membrane demonstrated a rejection fee of 18.94 ± 1.58% and a permeability of 0.91 ± 0.13 L/(h·bar·m²), whereas additionally exhibiting improved antifouling efficiency. These findings spotlight the potential of spin‑spray‑assisted LbL meeting as a promising route for skinny‑movie composite membrane fabrication.
Floor characterization was carried out utilizing a commercially out there AFM system outfitted with a NanoWorld Arrow‑CONTR AFM probe, a silicon cantilever with a power fixed of 0.2 N/m, operated involved mode. Lateral photographs have been used to visualise floor inhomogeneities throughout the scanned area. The NanoWorld AFM probe ensured steady tip–pattern interplay, enabling excessive‑high quality topographical and lateral power mapping. This text emphasizes the significance of choosing a dependable AFM probe for nanoscale membrane characterization.
