Title:
DIMMING FILM, DIMMER USING THE SAME, AND SCREEN
Document Type and Number:
Japanese Patent JP2018081133
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a dimming film including a transparent electrode that is excellent in productivity and flexibility, can exert a desired dimming function when voltage is applied, and enables lower driving voltage.SOLUTION: A dimming film can switch among two types or more in a direction of reducing (or increasing) haze as voltage applied to a dimming layer through a transparent electrode is increased. The transparent electrode is made from an organic and inorganic composite transparent conductive film including a conductive polymer and a conductive fiber, a surface resistance value of the composite transparent conductive film is 10-150 Ω/square, the maximum value of overall light transmittance at an applied voltage of 0-100 V is 40% or more (or the minimum value is 10% or less), and the minimum haze is 10% or less (or the maximum haze is 80% or more).SELECTED DRAWING: None
