Abstract
A method of creating a hydrophobic polymer membrane surface includes depositing a polymer material onto a heated carrier, using the heated carrier, transporting the polymer material past an electrode field generator, generating an electric field adjacent the carrier, using the electric field to form a pattern in the polymer material to form a patterned polymer membrane, rinsing the patterned polymer membrane in a first bath, and setting the pattern into the patterned polymer membrane in a second bath.
