Abstract
Poly(diallyldimethylammonium chloride) (PDDA) capped copper hexacyanoferrate nanoparticles (CuHCF NPs) with the controlled size are prepared following a precipitation method. While PDDA and CuHCF are not active at the cyclohexane/water interface, PDDA capped CuHCF NPs present synergistic property permitting them to stabilise oil-in-water emulsions for weeks. These latter can be considered as promising precursors for the development of new porous materials considering the fact that the NPs present some interests in the field of nuclear decontamination.
