현재 유기분산형 전계발광램프(EL)의 절연층 또는 유전층에 사용되는 고분자 소재는 시아노에틸화 탄수화물(시아노에틸 셀룰로오스, 시아노에틸 스타치 그리고 시아노에틸 풀루란)들과 불소계 고분자가 사용되고 있다.Currently, the polymer material used for the insulating layer or the dielectric layer of the organic light emitting electroluminescent lamp (EL) is made of cyanoethylated carbohydrates (cyanoethyl cellulose, cyanoethyl starch and cyanoethyl pullulan) and a fluorine-based polymer. have.

상기 시아노에틸화 탄수화물들은 위에서 열거한 대부분의 특성을 만족시키지만 근본적으로 흡습성이 커서, 제품의 내구성 및 가공성, 그리고 전기특성을 저해시킨다. 그리고 불소계 고분자는 흡습성은 낮으며 접착력과 유전율이 낮은 단점이 있다.The cyanoethylated carbohydrates satisfy most of the properties listed above, but are essentially hygroscopic, impairing the durability, processability, and electrical properties of the product. In addition, the fluorine-based polymer has a disadvantage of low hygroscopicity and low adhesion and dielectric constant.

따라서, 본 발명은 상기한 문제점을 해결하기 위해 안출된 것으로, 유기분산형 전계발광램프의 절연층 또는 유전층에 사용되어 유전특성이 향상되고, 수분에 대한 내성이 뛰어나며, 접착력이 뛰어난 유기분산형 전계발광램프의 고유전율 유기고분자를 제공하는 것을 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, it is used in the insulating layer or dielectric layer of the organic light emitting electroluminescent lamp to improve the dielectric properties, excellent resistance to moisture, excellent organic adhesion type electric field An object of the present invention is to provide a high dielectric constant organic polymer of a light emitting lamp.

상기한 목적을 달성하기 위한 본 발명은, 2-cyanoethylacrylate, allylyanide 및 methylmethacrylate의 삼원공중합체로 만들어지는 유기분산형 전계발광램프의 고유전율 유기고분자를 기술적 요지로 한다.The present invention for achieving the above object, the high dielectric constant organic polymer of the organic dispersion type electroluminescent lamp made of a terpolymer of 2-cyanoethylacrylate, allylyanide and methylmethacrylate.

여기서, 상기 2-cyanoethylacrylate, allylyanide 및 methylmethacrylate의 구성 성분비는 2:1:1의 비율로 합성되는 것이 바람직하다.Here, the constituent ratio of 2-cyanoethylacrylate, allylyanide and methylmethacrylate is preferably synthesized in a ratio of 2: 1: 1.

그리고, 상기 2-cyanoethylacrylate, allylyanide 및 methylmethacrylate의 삼원공중합체가 유기분산형 전계발광램프의 절연층 또는 유전층을 형성하는 것이 바람직하다.In addition, it is preferable that the terpolymer of 2-cyanoethylacrylate, allylyanide and methylmethacrylate form an insulating layer or a dielectric layer of an organic dispersion type electroluminescent lamp.

또한 , 상기 절연층 또는 유전층은 필름형상으로 형성되는 것이 바람직하다. 이에 따라, 유기분산형 전계발광램프의 유전특성이 향상되고 수분에 대한 내성이 뛰어나며, 접착력 및 유연성이 양호함과 동시에 가격이 저렴하다는 이점이 있다.In addition, the insulating layer or the dielectric layer is preferably formed in a film shape. Accordingly, there is an advantage in that the dielectric properties of the organic light emitting electroluminescent lamp are improved, the resistance to moisture is excellent, the adhesion and flexibility are good, and the price is low.

이하 첨부된 도면을 참조로 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

유기분산형 전계발광램프의 절연층 또는 유전층은 고유전율 고분자물질로 만들어져 절연성질을 띠게 되며, 상기 고유전율 고분자물질은 2-cyanoethylacrylate, allylyanide 및 methylmethacrylate의 삼원공중합체(이하 "CAM20"이라 칭한다.)로 만들어진다. 그리고 상기 "CAM20"은 접착력이 양호하고 유전율은 높으면서 흡습성이 낮다는 것이 실험적으로 입증된다.The insulating layer or the dielectric layer of the organic dispersion type electroluminescent lamp is made of high dielectric constant polymer material to have insulating properties. Is made with. And the "CAM20" is experimentally proved to have good adhesion, high dielectric constant and low hygroscopicity.

흡습성과 유전율은 일반적으로 비례관계를 갖는다. 따라서 유전율을 높이면서도 흡습성을 낮추기 위해서는 하나의 작용기로는 만족시킬 수 없으며, 화학 구조적으로 서로 보완 작용을 할 수 있는 두가지 이상의 작용기를 도입하여야 한다. 즉, 강한 소수성기을 나타내는 작용기와 높은 유전율을 나타내는 작용기를 필요로 한다. 기존의 소재에서는 일반적으로 탄수화물을 반복단위로 하는 물질을 사용하기 때문에 수분에 대한 친수성이 매우 크다. 이에 본 발명에서는 탄수화물이 아닌 acrylate계통의 물질을 사용하여 고분자를 합성하여 유기분산형 전계발광램프의 절연층 또는 유전층으로 사용하기 위해 이들의 물성을 조사하였다.Hygroscopicity and permittivity are generally proportional. Therefore, in order to increase the dielectric constant and lower the hygroscopicity, one functional group cannot be satisfied, and two or more functional groups that can complement each other in chemical structure must be introduced. That is, a functional group showing a strong hydrophobic group and a high dielectric constant are required. Conventional materials generally use carbohydrate repeating materials, so they are very hydrophilic. Accordingly, in the present invention, polymers were synthesized using acrylate-based materials, not carbohydrates, and their properties were investigated for use as an insulating layer or a dielectric layer of an organic light emitting electroluminescent lamp.

EL용 고유전율 유기고분자인 CAM20(2-cyanoethylacrylate, allylyanide 및 methylmethacrylate의 삼원공중합체)의 구성성분 중 2-cyanoethylacrylate와 allylyanide는 유전율이 큰 시아노기를 가지고 있으며, methylmethacrylate는 접착력을 증가시키기 위해 사용되었다. 여기서 2-cyanoethylacrylate:allylyanide: methylmethacrylate의 비율이 2:1:1일 때 EL에 가장 적합한 물성을 나타내었다.Among the constituents of CAM20 (terpolymers of 2-cyanoethylacrylate, allylyanide and methylmethacrylate), 2-cyanoethylacrylate and allylyanide have high dielectric constant cyano groups and methylmethacrylate was used to increase adhesion. Here, when the ratio of 2-cyanoethylacrylate: allylyanide: methylmethacrylate is 2: 1: 1, it showed the most suitable physical properties for EL.

다음은 몇가지 CAM20의 합성과정을 나타낸 것이다.The following shows the synthesis of some CAM20s.
