- Abstract
- Silver nanocrystals have been prepared by reacting silver nitrate with ascorbic acid in aqueous solution containing a low concentration of a commercial polynaphthalene sulfonate polymer (Daxad 19). Various crystalline morphologies have been obtained simply by tuning the reaction temperature. We have investigated the nanoparticle formation mechanism at three different temperatures by in situ and time resolved small angle X-ray scattering measurements. By modeling the scattering intensity with interacting spherical particles in a fractal-like polymerAg matrix, we found signatures of nucleation, growth and assembly of primary particles of about 1520 nm. We observed how the time evolution of both spatial correlations between primary particles and the dynamic fractal geometry of the polymerAg matrix could influence and determine both the aggregation mechanism and the morphology of forming nanostructures in solution.
