Abstract
An electrorheological fluid is provided. The electrorheological fluid includes polarizing particles and a dispersion medium in which the polarizing particles are dispersed. The polarizing particles may include silica particles. The dispersion medium may include silicon oil. The silicon oil may be modified silicon oil including at least one functional group selected from the group consisting of a hydroxyl group (—OH group), an amine group (—NH2 group), a mercapto group (—SH group), and a carboxy group (—COOH group).
Claims15
An electrorheological fluid comprising:
- polarizing particles comprising silica particles;
- and
- a dispersion medium in which the polarizing particles are dispersed, the dispersion medium comprising silicon oil having at least one functional group selected from the group consisting of a hydroxyl group (—OH group), an amine group (—NH2 group), a mercapto group (—SH group), and a carboxy group (—COOH group).
A method of producing electrorheological fluid, the method comprising:
- producing polarizing particles comprising silica particles;
- producing a dispersion medium comprising silicon oil having at least one functional group selected from a group consisting of a hydroxyl group (—OH group), an amine group (—NH2 group), a mercapto group (—SH group), and a carboxy group (—COOH group);
- and
- dispersing the polarizing particles in the dispersion medium.
A display comprising:
- a first electrode;
- a second electrode facing the first electrode;
- and
- electrorheological fluid filled in a gap between the first electrode and the second electrode, wherein the electrorheological fluid comprises:
- polarizing particles comprising silica particles;
- and
- a dispersion medium in which the polarizing particles are dispersed, the dispersion medium comprising silicon oil having at least one functional group selected from the group consisting of among a hydroxyl group (—OH group), an amine group (—NH2 group), a mercapto group (—SH group), and a carboxy group (—COOH group).
