| 发明名称 | Multiphase liquid composition for low voltage electrowetting device | ||
| 摘要 | A multi-phase liquid composition comprising a conductive liquid and a non-conductive liquid, said liquids being non miscible, wherein the conductive liquid comprises more than 90% up to 99.9% by weight of a first component having a surface tension above 45 mN/m and comprising water, salt and at least one freezing point lowering agent, and from 0.01% to less than 10% by weight of a second component having a surface tension below 30 mN/m and comprising at least one first compound, wherein said at least one first compound is a non ionic surfactant. | ||

| 主权项 | 1. A multi-phase liquid composition, comprising: a conductive liquid and a non-conductive liquid, said liquids being non miscible, wherein the conductive liquid comprises more than 90% up to 99.9% by weight of a first component having a surface tension above 45 mN/m and comprising water, salt and at least one freezing point lowering agent, and from 0.01% to less than 10% by weight of a second component having a surface tension below 30 mN/m and comprising at least one first compound, and wherein said at least one first compound is a non ionic surfactant, and wherein said non ionic surfactant is a polypropylene glycol having an average weight from 200 g/mol to 2000 g/mol. | ||
