Definitions

  • Patent Documents 2 and 3 disclose various organic solvents and ionic liquids as polar solvents used for electrowetting other than water. Further, it is disclosed that the polar solvent is selected based on the viscosity, the surface tension of the droplet, the conductivity, and the like.
  • Formamide can be used particularly preferably because it has a polar force component higher than a predetermined value and a high boiling point, so that the droplet operation by electrowetting occurs stably.
  • the position of the solvent 203 can be moved (controlled) not only in the direction of the arrow A shown in FIGS. 3A to 3D but also in the direction opposite to the arrow A by controlling the position of the electrode with the voltage.
  • CYTOP registered trademark, manufactured by Asahi Glass Co., Ltd.
  • SiO 2 spin coating
  • Formulas (1) and (1 ′) show Fokes formulas, and formula (2) shows extended Fowkes formulas.
  • the surface tension ( ⁇ ) can be defined for both the water-repellent film and the solvent.
  • the surface tension ( ⁇ L ) of the solvent can be determined by the Fokes equation shown in the equation (1) according to the dispersion component of the solvent ( ⁇ L d ), Polar component ( ⁇ L p ), and hydrogen bond component ( ⁇ L h ).
  • Table 7 shows the surface tension ( ⁇ L ) and the polar force component ( ⁇ L P ) of the solvent for Examples 1 to 6 and Comparative Examples 1 to 3 described above. Moreover, immediately after dropping the solvent and 30 minutes after the dropping, a voltage was applied to indicate whether or not the solvent was operated.
