Abstract

본 발명은 액정 베시클 및 이를 사용한 PDLC에 관한 것으로서, 본 발명에서는 한 분자내에 소수성과 친수성을 동시에 갖는 양성물질로부터 얻어지는 베시클의 내부에 액정 물질이 주입된 액정 베시클 및 한 쌍의 투명기판과, 그 내면에 설치된 한 쌍의 투명전극과, 그 내부에 주입된, 고분자 물질내에 액정 방울이 불연속 상태로 분산된 광조절물질을 포함하여 이루어지는 PDLC에 있어서, 상기 액정 방울이 액정 베시클인 것을 특징으로 하는 PDLC를 제공한다.The present invention relates to a liquid crystal vesicle and a PDLC using the same. In the present invention, a liquid crystal vesicle and a pair of transparent substrates in which a liquid crystal material is injected into a vesicle obtained from a positive material having both hydrophobicity and hydrophilicity in one molecule; A PDLC comprising a pair of transparent electrodes provided on an inner surface thereof and a light control material in which a liquid crystal droplet is dispersed in a discontinuous state in a polymer material injected therein, wherein the liquid crystal droplet is a liquid crystal vesicle. Provide PDLC.

본 발명의 액정 베시클을 채용한 PDLC는 전기장을 가하지 않았을 경우 광산란율이 높아 온-오프시 콘트라스트가 크게 향상된 것이다.The PDLC employing the liquid crystal vesicle of the present invention has a high light scattering rate when no electric field is applied, thereby greatly improving contrast on / off.
