Nanoparticles hybrid systems: interactions, local structure and mobility (Project of the TOP NANO 21 Innovation Committee)
Abstract
The project aims at an investigation of the stability and the onset of aggregation and/or phase separation in concentrated nanoparticle dispersions and polymer-particle mixtures in order to rationalize the relevant design parameters needed to obtain long-term stability of novel nanoparticle-polymer hybrid materials. This will be achieved primarily with a study of diffusion and re -agglomeration over a reasonable time by light, small-angle neutron and X-ray scattering methods, fluorecence lifetime analysis and spectral properties of the emission. In parallel model-nanoparticle suspensions will be studied with various technqiues to elaborate the fundamental mechanisms of diffusion, agglomeration and phase behavior, and a development of optical tools for an in-situ monitoring will be a major technical goal of the project.
