Superior performance of multilayered fluoropolymer films in low voltage electrowetting

► Multilayered hydrophobic dielectric featuring plasma-deposited fluorocarbon interlayer. ► Increased lifetime of the proposed multilayered (composite) top coating. ► High resistance to dielectric breakdown (visible as electrolysis). ► Improvement of electrowetting performance in long term application of AC and DC voltage. ► Persistence of dielectric properties checked by sensitive leakage current measurements.
