Title Platelet Janus particles with hairy polymer shells for multifunctional materials
Date 15.07.2014
Number 43582
Abstract A novel approach is developed for the large-scale synthesis of Janus particles with platelet geometry and dense polymer shells by employing simultaneous “grafting from” of hydrophilic and hydrophobic polymers using surface-induced ATRP in emulsion. The method is based on the fabrication of an emulsion consisting of a water solution of a hydrophilic monomer and a solution of a hydrophobic monomer in an organic solvent, which is stabilized by initiator-modified kaolinite particles. Two polymers are grafted simultaneously on the opposite faces of the kaolinite particle during polymerization. The synthesized core-shell particles have a clear Janus character. Due to its simplicity, the method can readily be upscaled for the synthesis of large amounts of Janus particles - up to several grams. The proposed approach can aid in the design of multifunctional hybrid Janus particles for different technological applications such as stabilization of fluid-fluid interfaces or design of chemically and topographically structured surfaces with of anti-icing behavior.
