Controlling adsorption density of polymer-stabilised metal nanoparticles at the oil–water interface

Interfacial density of polymer-stabilised platinum nanoparticles (< 10nm) used to stabilise O/W emulsion droplets can be controlled through excess polymer present in the suspension. [Display omitted] Emulsion droplets offer an alternative to solid supports as templates for the deposition of metallic nanoparticles. An emulsion interface provides the opportunity to exploit both sides of the nanoparticles and to utilise the liquid core as a microreactor in addition to forming a scaffold for encapsulation. However, despite the extensive literature studying a very broad range of factors influencing the characteristics of particle-stabilised (Pickering) emulsions, most reports focus on particles of diameters >100 nm and a very small proportions consider particles of diameters
