Abstract

Abstract : The structure control during the formation of films from nanoparticles is investigated. The particles are synthesized by miniemulsion polymerization with different ratios of methyl methacrylate and butyl methacrylate in the presence of silica nanoparticles. The structure of the hybrid particles is controlled by changing the surface properties of the silica through functionalization with 3‐methacryloxypropyltrimethoxysilane (MPS) and octadecyltrimethoxysilane (ODTMS). Fixation of the MPS‐silica due to polymerizable groups leads to a homogeneous distribution inside the polymer, while the inert alkyl chains of ODTMS result in segregation of the silica and the polymer. This difference in the structure is preserved during film formation and aggregation in films can be prevented effectively. Abstract : The structure control during the formation of films out of waterborne polymer/silica hybrid nanoparticles has been investigated. Differently functionalized silica particles lead to different degrees of aggregation during the formation of hybrid particles in miniemulsion polymerization. These structures can be preserved during the film formation process out of these hybrid particles.
