Approach to achieve controlled particle size synthesis of non-polar functionalised siloxane particles using a one-pot synthesis

Rowan McDonough, Daniel Mangos, Chris Hassam, Jonathan Campbell, David A. Lewis Flow chart of two one-pot methods for silica nanoparticle synthesis from functionalised silanesA scalable methodology that allows particles based on trialkoxy siloxanes with non-polar substituents to be synthesised in a one-pot reaction through the controlled addition of the reactants is reported. By dispersing the trialkoxy silane precursor prior to addition to the reaction solution, excellent control of particle size and dispersity can be achieved for systems not normally compatible with Stober methods.
