Polydimethylsiloxane coated glass frits for low-cost and reusable water–organic solvent separation
Abstract
A technique for functionalizing glass frits is described for use in separating water and organic solvents. The frits are coated with a hydrophobic–oleophilic silicone elastomer, giving rise to a reusable device that allows non-polar solvents to pass through but not water.
