Definitions
- the acrylate repeating unit included in the first polymer compound may include a repeating unit of Formula 1 below, and the vinyl repeating unit included in the first polymer compound may include a repeating unit of Formula 2 below. .
- Formula 1 or 2 is a substituted or unsubstituted alkyl group of 1 to 10 carbon atoms, aryl group of 6 to 10 carbon atoms, cycloalkyl group of 5 to 10 carbon atoms or alkyl group of 1 to 10 carbon atoms, respectively It may be an amide group, and R 2 may be each hydrogen or methyl group.
- Specific examples of the 'compound including two or more acrylate groups or methacrylate groups include 1,2-ethanediol diacrylate, 1,3-propanedi diacrylate, 1,3-butanedi diacrylate, 1 , 4-butanediol diacrylate, 1,5-pentanediacrylate, neopentyl diacrylate, 1,6-nucleic acid diol diacrylate, ethylene glycol diacrylate ,
- the protective layer may include the second polymer compound, the second polymer compound is an acrylate-based repeat unit or vinyl-based repeat It may include units. 100 parts by weight of the second polymer compound may include 50 to 99 parts by weight of the acrylate-based repeating unit or the vinyl-based repeating unit.
- the second polymer compound includes the polyfunctional aromatic vinyl-based repeating unit
- crosslinking between the second polymer compounds included in the protective layer may be increased, and the crosslinking density of the protective layer may be increased.
- the second polymer compound including the multifunctional aromatic vinyl-based repeating unit may form a more robust crosslinking and crosslinking structure than the above-described first polymer compound, and thus the electrophoretic particles have a high surface area.
- a protective layer having morphological stability and high solvent resistance can be formed.
- the aromatic compound including two or more vinyl groups include divinyl benzene, bis- (vinyl phenyl) ethane, or triallycyanurate. Preferably it may be divinyl benzene.
- the solvent in which the inorganic particles are dispersed or the solvent in which the particles of the core-shell structure are dispersed is an inorganic material.
- the particles or particles of the core-shell structure can be formed by adding to a water-soluble solvent and applying a conventional stirring method or a mixing method.
- the applied temperature may be a room temperature, for example, a temperature of 10 to 4 ( rc.
- the specific examples of the water-soluble solvent include distilled water, ultrapure water, alcoholic solvents, or a mixture thereof.
- the shape or structure of the electrophoretic part is not particularly limited, and may include, for example, a structure of a microcapsule or a microcup.
- the 'micro cup' refers to a cup-shaped recess formed in the electrophoretic display device.
- the 'micro cup' may mean a space surrounded by two electrodes facing each other and a partition wall formed between the electrodes.
- the 'microcapsule' refers to a spherical or elliptic spherical sealed container formed inside the electrophoretic display device and having a diameter of micrometer (um).
- the synthetic polymer was filtered by the above reaction, washed with water and aqueous ethanol solution, and the filtrate was put in a vacuum oven and dried for one day to prepare particles of a white odorless core-shell form.
- This electrophoretic particle slurry is injected into the IT0 cell (40 ⁇ X 45mm X 80um: width * length * height) that can pass current to the upper and lower plates, and as a core material for electrophoretic display while applying / removing voltage on the upper and lower parts. It was evaluated whether it could be used. Specific measurement items and measurement methods are as follows.
