Abstract
An electro-sensitive composition comprising a fluorine compound having a predetermined structure, and an electrically insulating medium capable of dissolving this fluorine compound when a voltage is applied thereto, is disclosed. This electro-sensitive composition has a straight chain or cyclic fluorocarbon, and fluorine compound particles possessing dissociable polarity, dispersed in an electrically insulating medium; by means of the application of a voltage to this electro-sensitive composition, the transparency and viscosity thereof can be easily adjusted.
