Transforming nano-science to nano-technology: Manipulating the size, shape, surface morphology, agglomeration, phases and defects of silver nano-particles under continuous flow conditions

, ,

Keywords: , , ,

Spinning disc processing (SDP) is an instantaneously scalable, continuous flow and high throughput flash nano-fabrication technology which embraces green chemistry metrics. It has been used to prepare silver nano-particles with remarkable control in size (5 – 200 nm), shape (spheroidal, acicular or agglomerate rosettes), surface characteristics, and phase (cubic versus hexagonal), along with imparting defects for particles > 10 nm diameters. The control is associated with changing the nature of the stabilising surfactant (respectively starch, polyethylene glycol and poly(4-vinylpyridine)), the concentration of the reactants, and flow rates.
