It is proposed to use time-resolved SANS (TR-SANS) to elucidate growth kinetics of composite latex-silica core-shell particles. These core-shell particles form the basis ofindustrial formulations in anti-reflective coatings, important for optimising efficiencies of solarcells: hence there are environmental, industrial and economic dimensions to this project. Theintention is to use contrast variation to highlight the growth of silica shells aroundmethacrylate-based polymer latex particles. Initial cryoTEM images indicate silicananoparticles (diameter 2-3 nm) form in situ before adsorbing to the latex templates, givingrise to the growth of silica shells. This experiment forms part of a 3 year program seeking toinvestigate the growth kinetics and properties of latex templated silica films, and this is the full kinetic study building on already accepted equilibrium work at ILL.
