Title:
ELECTROVISCOUS FLUID COMPOSITION AND CYLINDER DEVICE
Document Type and Number:
Japanese Patent JP2021020970
Kind Code:
A
Abstract:
To provide an electroviscous fluid composition and a cylinder device, that can obtain a large ER effect while suppressing current density.SOLUTION: The electroviscous fluid composition (8) of the present invention comprises a fluid (32) and particles (28) having ionic conductivity, wherein the particles (28) having ionic conductivity has a first layer (29) that constitutes a surface of the particle (28) and a second layer (30) that constitutes the inside of the particle (28) than the first layer (29), and an ionic conductivity of the first layer (29) is lower than the ionic conductivity of the second layer (30).SELECTED DRAWING: Figure 1
