Description
본 발명은 유연성이 우수한 고내열투명성 신규의 환상올레핀계 공중합체 및 이로부터 제조된 디스플레이, 태양전지 등의 용도에 적합한 플렉시블 기판에 관한 것이다.The present invention relates to a novel high heat-transparent transparency cyclic olefin copolymer and a flexible substrate suitable for use in displays, solar cells and the like prepared therefrom.
박막트랜지스터-액정디스플레이(TFT-LCD), 유기발광다이오드(OLED) 등 플렉시블 디스플레이, 플렉시블 태양전지 등은 기존의 유리 기반 평판형 제품에 비해서 박형 및 경량이고 충격에 강하며 휴대가 간편하다는 장점이외에 공간상, 형태상의 제약에서 상대적으로 자유로워 다양한 응용성을 확보할 수 있다는 점에서 더욱더 그 수요가 급증하고 있다.Flexible displays such as thin film transistor-liquid crystal displays (TFT-LCD), organic light emitting diodes (OLED), flexible solar cells, etc. are thinner, lighter, more impact-resistant, and more portable than conventional glass-based flat panels. The demand is increasing more and more in that it is relatively free from constraints of form and shape, and thus various applications can be secured.
이러한 플렉시블 디스플레이, 플렉시블 태양전지 등을 구현하기 위해서는 고내열투명성 플렉시블 기판 제조기술, 수분 및 산소에 대한 고차단성 부여기술, 투명전극 형성기술 등 많은 기술들이 복합적으로 필요하다. 대표적으로 고차단성을 부여하는 방법으로서는 가령 실리카계 산화물, 알루미늄계 산화물 등을 플렉시블 기판위에 진공증착, 스퍼터링 등 방법을 통해 박막으로 형성하고 다시 열경화성 수지를 코팅하는 작업을 반복함으로써 다층구조의 고차단성층을 형성시키는 방법이 있으며 투명전극 경우는 통상 인튬 틴 옥사이드(ITO), 인튬 징크 옥사이드(IZO) 등 산화물을 진공증착, 스퍼터링 방법 등에 의해 박막으로 형성시키고 있다. In order to implement such a flexible display and a flexible solar cell, many technologies such as a high heat-resistant transparent flexible substrate manufacturing technology, a high blocking technology for moisture and oxygen, and a transparent electrode forming technology are required in combination. Representative methods for providing high barrier properties include, for example, forming a thin layer of silica oxide, aluminum oxide, etc. on a flexible substrate by vacuum deposition, sputtering, or the like, and coating the thermosetting resin again, thereby repeating a high barrier layer having a multilayer structure. In the case of the transparent electrode, oxides such as indium tin oxide (ITO) and indium zinc oxide (IZO) are usually formed into thin films by vacuum deposition, sputtering, or the like.
고차단성 부여 및 투명전극을 형성시키는 공정에 필수적인 진공증착, 스퍼터링 등 공정은 불행히도 200℃이상의 높은 온도에서 실행되어야 하므로 자연 플렉시블 기판의 내열성이 극도로 요구되고 있다. 가령 플렉시블 기판의 주요 용도중 하나인 박막트랜지스터-액정디스플레이 생산 시 박막트랜지스터 어레이를 플렉시블 기판위에 구현하는 공정온도가 250℃이상 극히 고온이기 때문에 플렉시블 기판의 내열성은 더더욱 요청되고 있다. 이러한 내열성은 현재 유리전이온도 및 열팽창계수로서 이를 평가하고 있는데, 고내열성 플렉시블 기판을 제조하기 위해서는 최소 250℃이상, 바람직하게는 300℃이상의 높은 유리전이온도 및 최소 20ppm/℃이하, 바람직하게는 10ppm/℃이하의 낮은 열팽창계수를 가진 플라스틱 소재가 필요하다. The processes such as vacuum deposition and sputtering, which are essential for the process of imparting high barrier resistance and forming transparent electrodes, are unfortunately required to be performed at a high temperature of 200 ° C. or higher, so that the heat resistance of the natural flexible substrate is extremely demanded. For example, in the production of thin film transistor-liquid crystal display, which is one of the main uses of the flexible substrate, the heat resistance of the flexible substrate is increasingly required because the process temperature for implementing the thin film transistor array on the flexible substrate is extremely high above 250 ° C. This heat resistance is currently evaluated as a glass transition temperature and coefficient of thermal expansion, in order to manufacture a high heat resistant flexible substrate, a high glass transition temperature of at least 250 ℃, preferably at least 300 ℃ and at least 20ppm / ℃, preferably 10ppm Plastic materials with low coefficients of thermal expansion below / ° C are needed.
또한 이러한 플렉시블 기판에 적합한 플라스틱 소재는 상기 높은 유리전이 온도 및 낮은 열팽창계수를 가지는 내열성뿐만 아니라 광투과도 기준 90% 이상 우수한 투명성, 복굴절 기준 10㎚이하의 등방성 등 여러 물성이 요구되고 있다. In addition, a plastic material suitable for such a flexible substrate is required to have various physical properties such as heat resistance having a high glass transition temperature and a low coefficient of thermal expansion, excellent transparency of 90% or more based on light transmittance, and isotropy of 10 nm or less based on birefringence.
종래 연구개발의 유력한 대상이 되어온 플렉시블 기판용 플라스틱 소재로서는 폴리에틸렌테레프탈레이트, 폴리에틸렌나프탈레이트, 폴리카보네이트, 폴리에테르설폰, 폴리노르보르넨, 폴리이미드 등이 있다.Plastic materials for flexible substrates, which have been the main targets of conventional research and development, include polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyethersulfone, polynorbornene, polyimide and the like.
폴리이미드는 360℃ 수준의 높은 유리전이온도 및 17ppm/℃ 수준의 낮은 열팽창계수를 가지므로 내열성 측면에서 큰 장점을 가지고 있으나 원료 및 제조원가가 높고 노란색을 띄고 있어 바람직하지 않다. 폴리에틸렌테레프탈레이트, 폴리에틸렌나프탈레이트 등 폴리에스테르 수지는 열팽창계수는 13 내지 15ppm/℃로서 비교적 낮은 편이나 유리전이온도가 80 내지 120℃ 수준으로 매우 낮고, 150nm이상 높은 복굴절을 가지기 때문에 결국 플렉시블 기판에 적합한 플라스틱 소재 대상 에서 제외되고 있다. 폴리카보네이트 경우 광투과도 90%의 투명성, 10㎚이하 낮은 복굴절 측면에선 긍정적이나 유리전이온도가 150 내지 200℃ 수준으로 매우 낮아 역시 바람직하지 않다. 또한 폴리에테르설폰 경우 가령 스미토모배이크라이트사의 폴리에테르설폰 기판(상품명 Sumilite FS-1300)은 광투과도 89%의 투명성, 10㎚이하의 낮은 복굴절을 가지는 장점이 있으나 유리전이온도가 223℃로서 폴리카보네이트 대비 우수하지만 역시 요구하는 250℃이상의 유리전이온도 조건에는 부합하지 못한 단점이 있다. 또한 대한민국 공개특허 10-2010-0091624에서는 환상올레핀계 고분자 화합물 및 그 제조 방법에서는 기존에 사용된 수지인 1,4,5,8-디메타노-1,2,3,4,4a,5,8,8a-옥타하이드로나프탈렌이 가지고 있는 제조공정의 비 용이성과 높은 비용문제를 해결하기 위해 보다 간단한 방법으로 동일한 물성을 낼 수 있는 환상올레핀계 고분자 화합물을 제시하였으나 유리전이온도가 64 내지 177℃로 고내열성 플렉시블 기판을 제조하기 위한 최소의 유리전이온도인 250℃에 못 미치는 단점이 있다. 마찬가지로 대한민국 공개특허 10-1991-0016790에서 에틸렌과 환상올레핀을 공중합하여 환상올레핀계 랜덤공중합체를 고농도로 효율적으로 제조하는 방법을 제시하였으나 랜덤공중합체의 유리전이온도가 20 내지 200℃에 불과하여 요구하는 250℃의 유리전이온도 조건에 미치지 못하는 단점이 있다. Since polyimide has a high glass transition temperature of 360 ° C. and a low thermal expansion coefficient of 17 ppm / ° C., polyimide has great advantages in terms of heat resistance, but is not preferable because of its high raw material and manufacturing cost and yellow color. Polyester resins such as polyethylene terephthalate and polyethylene naphthalate have relatively low thermal expansion coefficients of 13 to 15 ppm / ° C, but have a very low glass transition temperature of 80 to 120 ° C. and high birefringence of 150 nm or more. Plastic material is excluded from the target. In the case of polycarbonate, light transmittance is positive in terms of transparency of 90% and low birefringence of less than 10 nm, but the glass transition temperature is very low, such as 150 to 200 ° C. In addition, in the case of polyether sulfone, for example, Sumitomo Bakelite's polyether sulfone substrate (trade name Sumilite FS-1300) has the advantage of having 89% transparency of light and low birefringence of less than 10 nm, but the glass transition temperature is 223 ° C. Compared with the excellent glass transition temperature conditions of 250 ℃ or more, but also has the disadvantage that does not meet. In addition, the Republic of Korea Patent Publication No. 10-2010-0091624 In the cyclic olefin polymer compound and its manufacturing method 1,4,5,8-dimethano-1,2,3,4,4a, 5, In order to solve the inefficiency and high cost of the manufacturing process of 8,8a-octahydronaphthalene, a cyclic olefin polymer compound having the same physical properties can be proposed in a simpler method, but the glass transition temperature is 64 to 177 ° C. There is a disadvantage that is less than 250 ℃, the minimum glass transition temperature for producing a high heat-resistant flexible substrate. Likewise, Korean Patent Publication No. 10-1991-0016790 proposes a method for efficiently preparing cyclic olefin random copolymers by copolymerizing ethylene and cyclic olefins at high concentration, but the glass transition temperature of the random copolymer is only 20 to 200 ° C. There is a disadvantage that does not reach the glass transition temperature condition of 250 ℃.
반면 프로메러스사의 폴리노르보르넨 기판(상품명 Appear 3000)과 같은 환상올레핀계 수지 기판 경우 유리전이온도 330℃의 높은 내열성, 광투과도 92%의 우수한 투명성, 10㎚이하 복굴절의 우수한 등방성을 가지고 있어 플렉시블 기판에 적합한 강력한 후보 소재로서 큰 기대를 모으고 있다. 그러나 불행히도 이러한 환상올레핀계 수지 기판 경우 플렉시블 기판의 기본 물성이라 할 수 있는 유연성이 매우 부족한 문제점이 있고 또한 내열성의 또 하나의 척도인 열팽창계수가 100 내지 200ppm/℃수준으로 매우 높아 그 해결이 매우 절실히 요청되고 있다.On the other hand, cyclic olefin resin substrates such as Pronorus' polynorbornene substrate (trade name Appear 3000) have high heat resistance of glass transition temperature of 330 ° C, excellent transparency of 92% and excellent isotropy of birefringence of less than 10nm. It is a great expectation as a strong candidate material suitable for a flexible substrate. Unfortunately, however, such cyclic olefin resin substrates have a problem that the flexibility of the basic properties of the flexible substrate is very insufficient, and the thermal expansion coefficient, which is another measure of heat resistance, is very high at a level of 100 to 200 ppm / ° C. It is requested.
본 발명은 기존의 고내열성 플렉시블 기판을 제조하기 위한 플라스틱 소재가 가지고 있는 단점인 높은 열팽창계수와 낮은 투명성, 250℃이하의 유리전이온도, 낮은 유연성을 해결하기 위한 신규의 환상올레핀 공중합체 및 이로부터 제공된 플렉시블 기판을 제공하는 것을 그 목적으로 한다.

[표 2]TABLE 2
상기 표 2에서 보이는 바와 같이, 실시예 1 내지 실시예 10을 살펴볼 때, 카르복실산기 또는 카르복실산금속염기 함유 환상올레핀계 공중합체는 탁월한 유연성 및 극히 낮은 열팽창계수를 가질 뿐 만 아니라 종래 환상올레핀계 수지의 장점인 높은 유리전이온도에 의한 내열성, 우수한 투명성 및 등방성을 동시에 가짐을 알 수 있다. As shown in Table 2, when looking at Examples 1 to 10, the carboxylic acid group or metal carboxylate-containing cyclic olefin copolymer not only has excellent flexibility and extremely low coefficient of thermal expansion, but also conventional cyclic olefin It can be seen that it has both heat resistance, excellent transparency and isotropy due to the high glass transition temperature, which are advantages of the resin.
특히 실시예 3 내지 실시예 6과 비교예 1을 비교해 볼 때 유리전이온도, 투명성 및 등방성면에서는 상호 유사하지만 유연성 및 열팽창계수에 있어서 매우 큰 차이가 있음을 알 수 있다. In particular, when comparing Examples 3 to 6 and Comparative Example 1, it can be seen that the glass transition temperature, transparency and isotropy are similar to each other, but there are very large differences in flexibility and coefficient of thermal expansion.
또한 실시예 3, 실시예 4 및 비교예 2와 비교해 볼 때 유리전이온도, 투명성, 등방성, 유연성 면에서는 상호 유사하지만 카르복실산기 또는 카르복실산금속염기 도입에 따라 유연성이 더욱 개선되고 열팽창계수에 있어서는 극명한 차이를 볼 수 있다. In addition, compared with Examples 3, 4 and Comparative Example 2, the glass transition temperature, transparency, isotropy and flexibility are similar to each other, but the flexibility is further improved by the introduction of a carboxylic acid group or a metal carboxylate base and the coefficient of thermal expansion You can see the difference.
또한 실시예 6과 실시예 8, 실시예 9을 비교하였을 때 금속이온으로 중화하지 않은 실시예 8, 실시예 9의 경우 열팽창계수가 비교적 높거나 유리전이온도가 떨어져 기판용 재료로 사용하기에 부적합하다는 것을 알 수 있다.
In addition, when Example 6, Example 8, and Example 9 were compared, the Examples 8 and 9, which were not neutralized with metal ions, were not suitable for use as substrate materials due to their relatively high thermal expansion coefficient or low glass transition temperature. You can see that.
