We use capillary microfluidics for precise formation of double emulsion templates to fabricate core-shell particles; for example, by polymerizing a droplet middle layer to form capsules with a consolidated membrane. We use this strategy to fabricate capsules with potential application in enhanced oil recovery. We create capsules with fluorinated crosslinked polymers using in-situ photopolymerization to create inert membranes with ultra-low permeability. We include acrylate linkages in the polymer matrix as degradable components; these acrylate linkages are oxidized to present a simple mechanism for timed release of actives. Additionally, we use microfluidics to fabricate oil-absorbing core-shell particles with a hydrophobic porous core protected by a hydrophilic shell; the shell is made hydrophilic by silica nanoparticles adsorbed at the surface. These particles have great promise for use in oil remediation or EOR applications.
