Abstract
A method for the preparation of hydrophilic elastomers involves the synthesis of polydimethylsiloxane with tunable hydrophilic surface properties. An elastomeric monolith with desired hydrophilic properties is produced by combining a polyethylene oxide polymeric surfactant additive with a PDMS base and curing agent during polymerization. The surfactant chain segment lengths are varied to control the hydrophobic/hydrophilic balance.
