A Facile Surfactant-Free Strategy to Construct Porous Structures with Hydrophobic and Hydrophilic Domains from Monomer/Water Mixtures

Abstract

In Pickering emulsions colloidal nanoparticles can efficiently stabilize water/oil mixtures and many examples are present in a wide range of applications. However the low mechanical properties of the final devices are limiting their uses. Here we propose a strategy to use colloidal nanoparticle at hydrohobic monomer-water interface able to form biphasic, stable and porous structures during monomer polymerization. The final devices present two separate phases with different water affinities that make them extremely promising in many different fields. The strategy described present high versatility and can be applied to different monomers and nanoparticles opening the doors to many different applications.
