Versatile phosphonium-catechol dispersant for inorganic nanoparticle stability across diverse media and manufacturing processes.

ABSTRACT: Inorganic nanoparticles (NPs) have significant potential for various applications; however, achieving stable dispersion in organic media and polymers remains a key challenge for their industrial use. We developed a novel dispersant, tributyl(3-((3,4-dihydroxyphenylamino)-3-oxopropyl)phosphonium chloride) (TPC), which contains a catechol group for strong NPs binding and a phosphonium chloride moiety for effective dispersion. The versatility of TPC was demonstrated by stabilizing TiO₂, Fe₂O₃, and ZnO NPs in methanol using bead milling, as confirmed by TGA, DLS, zeta potential, and TEM analyses. In addition, TPC exhibited broad compatibility across solvents with varying dielectric constants. Furthermore, several hybrid polymer films were prepared by casting and photosolidification from monome
