Flash Nano Precipitation to Prepare Inorganic Nanoparticles

A rapidprecipitation technique,confined mixing induced nano-precipitation is a novel,one-step method for producing nanoparti-cles(NPs)with adjustable size,high specific surface area,sta-ble morphological structure and excellent surface and interfaceperformance.It is also called flash nano precipitation(FNP)asits mixing time is on the millisecond scale.A typical FNP processstarts withrapidly mixing a good solvent stream dissolving am-phiphilic copolymer and an anti-solvent stream of the copolymerin the space-confined and tiny chamber.The self-assembly andstability of the organic nanoparticles are achieved via rapid super-saturation and precipitation.
