One-pot facile synthesis of half-cauliflower amphiphilic Janus particles with pH-switchable emulsifiabilities

Abstract

A facile synthesis strategy for generating two types of highly uniform amphiphilic polymer Janus particles, spherical seeds and half-cauliflower particles, is first presented. Both of the submicron particles possessing pH-switchable emulsifiabilities can change their amphiphilicities/shapes and induce phase inversion of emulsions in response to pH values of solution.
