Macroporous Polymer Beads and Monoliths From Pickering Simple, Double, and Triple Emulsions

Abstract

Various polymeric materials based on simple, double, and triple emulsions stabilized solely by dichlorodimethylsilane (DCDMS)-modified amorphous silica nanoparticles of well-controlled surface hydrophobicities or organo-modified Laponite clay nanoparticles are described. Magnetic and fluorescent polymer beads having different morphologies are fabricated from double-emulsion templates. Polymer foams based on Pickering emulsions are fabricated and functionalized using different materials such as sporopollenin and zinc metal particles. Suspension polymerization of both oil phases of a novel Pickering triple emulsion results in the formation of new porous hierarchical structures. Polymer foams and beads based on novel nonaqueous Pickering simple and double emulsions are fabricated.
