본 발명에 의하면, 종래와 달리, 용액흡착방식을 이용함으로써, 보다 정량적이고 균일하게 입자에 외첨제를 흡착시킬 수 있을 뿐만 아니라, 화학적 결합에 의하므로, 내구성을 현저히 향상시킬 수 있으며, 용액흡착방식으로 염산, 글루타르알테하이드 및 아미노기가 형성된 이산화티타늄과 입자를 최적의 함량비율로 반응시킴으로써, 입자의 내구성 및 유동성을 현저히 향상시킬 수 있는 장점이 있다.
The present invention relates to an electronic paper using particles with a titanium dioxide external additive prepared by surface treatment of the electronic paper using particles with titanium dioxide external additive method and this, bear on the second solvent was added to the titanium dioxide having an amino group after the addition reaction step of preparing particles, dispersed to prepare a reaction solution; And it characterized in that comprising; and a surface treatment step of reacting the particles by the addition of hydrochloric acid and glutaric Alte hydroxide in the reaction solution was prepared.
According to the present invention, unlike the prior art, by using a solution adsorption method, not only it can be more quantitative and adsorbing the external additive to uniform particles, because of the chemical bonding, and to improve the durability remarkably, solution adsorption method with hydrochloric acid, glutaric Alte hydroxy and amino groups are formed by reacting a titanium dioxide particle and the optimal content ratio, there is an advantage that can significantly improve the durability and the flowability of the particles.
