摘要: Water or aqueous electrolytes are the dominant components in electrowetting on dielectric (EWOD)-based microfluidic devices. Low thermal stability, evaporation, and a propensity to facilitate corrosion of metal parts integrated circuits electronics drawbacks solutions. The alternative use ionic liquids (ILs) as agents EWOD-based applications devices could overcome these limitations. Efficient EWOD be developed using task-specific ILs. In this regard, fundamental study properties ILs is essential. Therefore 19 different liquids, including mono-, di-, tricationic, plus mono- dianionic were examined. All tested showed various magnitudes an amorphous flouropolymer layer. effects IL structure, functionality, charge density studied. enhanced stability at higher ...
