Abstract
Description
본 발명은 액상의 분산안정제를 포함하는 분극입자 현탁액, 이를 이용한 투과도 가변 필름 및 그 제조방법에 관한 것으로, 분극입자를 안정하게 분산시켜주는 액상의 분산안정제가 현탁액의 매체 역할을 동시에 수행할 수 있고, 이 액상의 분산안정제가 고분자 수지와 혼합되지 않으면서 현탁액의 액적 형태로 고분자 수지 내에 분산되어 있는 투과도 가변 필름 및 그 제조 방법에 관한 것이다.The present invention relates to a polarized particle suspension containing a liquid dispersion stabilizer, a variable permeability film using the same, and a method for manufacturing the same. , This liquid dispersion stabilizer is dispersed in the polymer resin in the form of droplets of suspension without being mixed with the polymer resin, and relates to a variable transmittance film and a manufacturing method thereof.
분극입자 현탁액을 이용한 투과도 가변 기술은 입자가 전기장 방향에 따라 배열함으로써 가시광선 영역의 투과율을 변화시켜 줌으로써 투과하는 빛의 차단 정도를 조절할 수 있는 특징이 있다. 그런데 액체의 경우에는 건축물 창호, 차량용 창호 등에 적용을 위해 대형화 할 경우, 중력이나 외부의 압력에 의해 부풀거나 눌리게 되어 빛 투과량이 국소적으로 일정하지 않고 불균질한 상태가 될 수 있다. 이를 개선하기 위하여 분극입자 현탁액을 액적 형태로 포함하는 필름을 개발하기 위한 노력이 경주되어 왔으며, 대한민국 특허출원 제 10-1992-0011659호(광변광 현탁액이 고분자 수지 내에 분산된 투과도 가변창용 필름 및 그 제조방법) 및 대한민국 특허출원 제10-1993-0702534호(캡슐화된 액체 현탁액을 함유한 필름, 이 필름을 포함환 광밸브 및 상기 필름의 제조 방법)를 통하여 대형화를 위한 분극입자 현탁액을 포함하는 필름화 기술이 개발되기 시작하였다. 전술한 특허에서는 현탁액과 고분자 수지 용액을 혼합하고 코팅한 후 용매 증발에 의한 상분리 방법에 의해 현탁액이 고분자 수지 내에 액적 형태로 분리되어 고형화된 필름 형태로 만들어지게 된다. 반면, 후술한 특허에서는 현탁액과 가교반응 가능한 중합체 기질을 에멀젼 형태로 혼합한 후, 필름 형태로 코팅한 다음 가교 반응을 시켜줌으로써 필름을 고형화하여 최종적으로 투과도 가변 필름을 형성하는 방법이다.Transmittance variable technology using a polarized particle suspension is characterized in that the degree of blocking of transmitted light can be adjusted by changing the transmittance in the visible ray region by arranging the particles according to the direction of the electric field. However, in the case of liquid, when large-sized for application to building windows, vehicle windows, etc., it is inflated or pressed by gravity or external pressure, so that the amount of light transmission is not uniform locally and may become inhomogeneous. In order to improve this, efforts have been made to develop a film containing a suspension of polarized particles in the form of droplets, and Korean Patent Application No. 10-1992-0011659 (a film for variable transmittance window in which a light-changing suspension is dispersed in a polymer resin and its Manufacturing method) and Korean Patent Application No. 10-1993-0702534 (Film Containing Encapsulated Liquid Suspension, Ring Light Valve Including the Film and Manufacturing Method of the Film) Fire technology began to develop. In the aforementioned patent, the suspension and the polymer resin solution are mixed and coated, and then the suspension is separated in the form of droplets in the polymer resin by a phase separation method by solvent evaporation to form a solidified film. On the other hand, in the patents described later, a suspension and a crosslinkable polymer matrix are mixed in an emulsion form, coated in a film form, and then solidified by a crosslinking reaction to finally form a variable permeability film.
한편, 분극입자는 음으로 하전된 I3 - 혹은 I5 -를 포함하는, 1 마이크로 이하 크기이며, 막대 형태인 형상 이방성 입자로써 입자들끼리 서로 응집하는 특성이 있기 때문에 이를 현탁매 내에 안정적으로 분산시키기 위해서는 분산안정제가 반드시 요구된다. 이러한 분산안정제는 분극입자에 결합하는 결합부(anchoring group)와 현탁매에 용해되는 용해부(solubilizing 혹은 stabilizing group)를 포함하고 있어서 분극입자에 견고하게 결합하고 현탁매 내에 용해되어 분극입자가 서로 응집되지 않고 안정적으로 부유되도록 도와주는 역할을 한다. 또한, 필름화하는 경우에는 현탁매와 마찬가지로 분산안정제의 용해부는 필름의 기질인 고분자 수지와는 상용성(compatibility) 혹은 혼합성(miscibility)이 낮아서 서로 쉽게 혼합되지 않아야 한다. 이러한 특성을 위하여 기존의 방법에서는 분자량이 100,000 이상으로 큰 고분자 분산안정제를 사용하였으나, 이 경우 현탁매에 용해하기 쉽지 않으며, 용해된 경우에도 점도가 높아지므로 전기에 의해 입자가 회전하거나 복귀하는 반응속도가 느려지는 단점이 있었다.On the other hand, polarized particles are rod-shaped shape anisotropic particles containing negatively charged I 3 - or I 5 - , with a size of less than 1 micron, and are stably dispersed in a suspension medium because the particles have a property of aggregating with each other. To achieve this, a dispersion stabilizer is required. The dispersion stabilizer includes an anchoring group that binds to the polarized particles and a solubilizing or stabilizing group that dissolves in the suspension medium, so that it firmly binds to the polarized particles and dissolves in the suspension medium so that the polarized particles aggregate with each other. It plays a role in helping to float stably without falling. In addition, in the case of film formation, like the suspension medium, the dissolving part of the dispersion stabilizer should not be easily mixed with the polymer resin, which is the substrate of the film, due to low compatibility or miscibility. For this characteristic, in the existing method, a high molecular weight dispersion stabilizer of 100,000 or more was used, but in this case, it is not easy to dissolve in the suspension medium, and even when dissolved, the viscosity is high, so the reaction rate of rotation or return of the particles by electricity had the downside of being slow.
본 발명에서는 이를 해결하기 위하여, 상온에서 액체이며, 분극입자에 대한 결합부와 함께 용해부를 갖는 액상의 분산 안정제를 사용함으로써, 별도의 현탁매를 사용하지 않거나 쉽게 용해되고, 반응속도도 개선된 분산안정제를 사용한 투과도 가변 필름 및 그 제조방법을 제공하고자 한다.In the present invention, in order to solve this problem, by using a liquid dispersion stabilizer that is liquid at room temperature and has a dissolving portion as well as a bonding portion for polarized particles, a dispersion that does not use a separate suspension medium or is easily dissolved and has improved reaction rate. It is intended to provide a variable transmittance film using a stabilizer and a manufacturing method thereof.
따라서 본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로, 본 발명의 목적은 종래 고분자 분산안정제를 사용할 경우 발생할 수 있는 용해의 어려움 및 고점도의 문제를 해결하기 위하여 결합부(anchoring group)와 용해부(solubilizing group)로 이루어진 액상의 분산안정제를 포함하는 분극입자 현탁액을 제공하는 것이다.Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to solve the problem of difficulty in dissolving and high viscosity that may occur when using a conventional polymer dispersion stabilizer. It is to provide a polarized particle suspension containing a liquid dispersion stabilizer composed of a solubilizing group.
또한, 본 발명의 또 다른 목적은 상기 분극입자 현탁액을 이용함으로써 분극입자 현탁액의 액적을 형성하게 되며, 전계 인가에 따라 투과도를 조절할 수 있는 투과도 가변 필름 및 그 제조 방법을 제공하는 것이다.In addition, another object of the present invention is to provide a variable transmittance film and a method for manufacturing the same, wherein droplets of the polarized particle suspension are formed by using the polarized particle suspension and the transmittance can be adjusted according to the application of an electric field.
상기와 같은 목적을 달성하기 위한 본 발명은, 결합부(anchoring group) 및 용해부(solubilizing group)로 이루어진 액상의 분산안정제를 포함하는 분극입자 현탁액을 제공한다.To achieve the above object, the present invention provides a polarized particle suspension containing a liquid dispersion stabilizer composed of an anchoring group and a solubilizing group.

본 발명에 의하면, 종래 고분자 분산안정제를 사용할 경우 발생할 수 있는 용해의 어려움 및 고점도의 문제를 해결한 분극입자 현탁액을 이용함으로써 분극입자 현탁액의 액적을 형성하게 되며, 전계 인가에 따라 투과도를 조절할 수 있는 투과도 가변 필름을 제공할 수 있으며, 제조공정을 좀 더 단순화할 수 있을 뿐만 아니라 현탁액의 점도를 낮춰 줌으로써 반응속도를 개선할 수 있다.According to the present invention, by using a polarized particle suspension that solves the problems of dissolution difficulty and high viscosity that may occur when using a conventional polymer dispersion stabilizer, droplets of the polarized particle suspension are formed, and the transmittance can be adjusted according to the application of an electric field It is possible to provide a variable permeability film, and to further simplify the manufacturing process, as well as improve the reaction rate by lowering the viscosity of the suspension.

However, it should be understood that this is not intended to limit the present invention to specific embodiments, and includes all transformations, equivalents, and substitutes included in the spirit and technical scope of the present invention.

본 발명에서 극성은 상대적인 극성을 의미하며 마찬가지로 비극성은 상대적인 비극성을 의미한다. 또한 상용성이 낮다는 것은 고분자 물질 및 전분자 물질의 혼합에 있어서 유사한 것이 유사한 것을 녹인다(Like dissolve like)는 기본 개념에 덧붙여, 용해도 파라미터가 크게 차이 나는 경우를 의미한다. Hansen에 의하면 전체적인 용해도 파라미터는 아래와 같은 식에 의해 결정되어지며, 여기서 δ d , δ p , δ h 는 각각 분산력(dispersion force), 극성력(polar force), 수소결합력(hydrogen bonding force)을 의미한다. 따라서 전체적인 용해도 파라미터가 유사하더라도 극성력이나 수소결합력에 의한 용해도 파라미터 수치가 달라지면 용해도가 변하게 된다.In the present invention, polarity means relative polarity, and similarly, non-polarity means relative non-polarity. In addition, low compatibility means a case in which solubility parameters differ greatly in addition to the basic concept of like dissolve like in mixing polymeric substances and whole molecular substances. According to Hansen, the overall solubility parameter is determined by the following equation, where δ d , δ p , and δ h represent the dispersion force, polar force, and hydrogen bonding force, respectively. . Therefore, even if the overall solubility parameters are similar, the solubility changes when the solubility parameter values due to polar forces or hydrogen bonding forces are different.
δ 2 = δ D 2 + δ P 2 + δ H 2 δ 2 = δ D 2 + δ P 2 + δ H 2
위의 용해도 파라미터에서 고분자와 용매, 혹은 고분자와 고분자 사이의 친화성 정도는 각 결합력의 차이로 표시할 수 있으며, Skaarup에 의하면 실험적으로 아래와 같은 식으로 발전시켰다. 여기서 Ra는 용해도파라미터 차이, 하첨자 1은 용매 혹은 고분자, 하첨자 2는 고분자이다. 용해도 파라미터 차이가 감소하면 고분자와 용매 혹은 고분자와 고분자 사이의 친화성이 높다는 것을 의미한다.In the above solubility parameter, the degree of affinity between the polymer and the solvent or between the polymer and the polymer can be expressed as the difference in each binding force, and according to Skaarup, it was experimentally developed as follows. Here, R a is the solubility parameter difference, subscript 1 is the solvent or polymer, and subscript 2 is the polymer. A decrease in the solubility parameter difference means that the affinity between the polymer and the solvent or between the polymer and the polymer is high.
(R a ) 2 = 4(δ D2 δ D1 )2 + (δ P2 δ P1 )2 + (δ H2 δ H1 )2 (R a ) 2 = 4( δ D2 δ D1 ) 2 + ( δ P2 δ P1 ) 2 + ( δ H2 δ H1 ) 2
여기서 Ra는 고분자의 용해도 반경 R0와 비교할 수 있으며, 상대적인 에너지 차이(Relative Energy Difference, RED)로 아래와 같이 표시할 수 있다. RED 값이 0이면 에너지 차이가 없는 것이며, 1보다 작으면 친화성이 좋은 것이며, 그 값이 1이면 경계상태임을 나타내고, 그 값이 1이상이면 친화성이 낮은 상태를 의미한다.Here, R a can be compared with the solubility radius R 0 of the polymer, and can be expressed as the Relative Energy Difference (RED) as follows. If the RED value is 0, there is no energy difference, if it is less than 1, the affinity is good, if the value is 1, it indicates a boundary state, and if the value is 1 or more, it means a state with low affinity.
RED = R a / R 0 RED = R a / R 0
이하 본 발명에 따른 액상의 분산안정제를 포함하는 분극입자 현탁액, 이를 이용한 투과도 가변 필름 및 그 제조방법에 대하여 상세히 설명한다.Hereinafter, a polarized particle suspension containing a liquid dispersion stabilizer according to the present invention, a variable transmittance film using the same, and a manufacturing method thereof will be described in detail.
먼저, 본 발명에서는 결합부(anchoring group) 및 용해부(solubilizing group)로 이루어진 액상의 분산안정제를 포함하는 분극입자 현탁액을 제공한다.First, the present invention provides a polarized particle suspension containing a liquid dispersion stabilizer composed of an anchoring group and a solubilizing group.
상기 결합부는 분극입자와 수소결합에 의해 결합되어 잡아주며, 용해부는 액상의 형태로 분극입자의 브라운 운동을 가능하게 하고, 매트릭스를 구성하는 고분자 수지에 비해 상대적으로 비극성이어서 극성인 고분자 수지에 대하여 분리된 상을 유지하며, 따라서 분극입자가 분산된 액상의 현탁액이 고분자 수지 내에 액적 형태로 분포된다.The coupling part binds and holds the polarized particles by hydrogen bonding, and the dissolving part enables Brownian motion of the polarized particles in the form of a liquid, and is relatively non-polar compared to the polymer resin constituting the matrix, so it is separated from the polar polymer resin. Therefore, the liquid suspension in which the polarized particles are dispersed is distributed in the form of droplets in the polymer resin.
이때, 상기 결합부는 하기 [화학식 1] 내지 [화학식 4]에서 선택된 어느 하나의 것으로 표시되는 화합물일 수 있다.In this case, the bonding unit may be a compound represented by any one selected from [Formula 1] to [Formula 4].

[화학식 3] [화학식 4][Formula 3] [Formula 4]
(상기 화학식 1 내지 4에서, X는 N, O, F 또는 S이고, m은 2 내지 20 사이의 정수이며, n은 1 내지 5 사이의 정수이다)(In Formulas 1 to 4, X is N, O, F or S, m is an integer between 2 and 20, and n is an integer between 1 and 5)
상기 용해부는 하기 [화학식 5] 내지 [화학식 9]에서 선택된 어느 하나의 것으로 표시되는 화합물일 수 있다.The dissolving unit may be a compound represented by any one selected from the following [Formula 5] to [Formula 9].

(상기 화학식 5 내지 9에서, o는 30 내지 200 사이의 정수이며, p는 4 내지 15 사이의 정수이다)(In Chemical Formulas 5 to 9, o is an integer between 30 and 200, and p is an integer between 4 and 15)
상기 용해부는 비닐트리메틸실란(vinyltrimethylsilane), 알릴트리메틸실란(allyltrimethylsilane), 비닐옥시트리메틸실란(vinyloxytrimethylsilane), 트리메톡시비닐실란(trimethoxyvinylsilane) 및 트리에톡시비닐실란(triethoxyvinylsilane)으로 이루어진 군으로부터 선택된 1종 이상의 것일 수도 있다.The dissolving part is one or more selected from the group consisting of vinyltrimethylsilane, allyltrimethylsilane, vinyloxytrimethylsilane, trimethoxyvinylsilane and triethoxyvinylsilane. It may be.
상기 분산안정제는 상온에서 액체 상태로서, 결합부는 -OH, -NH, -SH를 포함하여 분극입자 표면에서 수소 결합이 가능하고, 용해부는 상대적으로 긴 알킬 사슬 또는 알킬 곁사슬을 가지고 있어서 비극성 특성을 나타내어 극성인 필름의 고분자 수지와 상용성이 낮은 것을 특징으로 한다.The dispersion stabilizer is in a liquid state at room temperature, and the bonding portion includes -OH, -NH, and -SH, and hydrogen bonding is possible on the surface of the polarized particle, and the dissolving portion has a relatively long alkyl chain or alkyl side chain, so it exhibits non-polar characteristics. It is characterized by low compatibility with the polymer resin of the polar film.
상기 액상의 분산안정제는 수평균 분자량이 3,000 내지 60,000 사이인 것을 특징으로 하며, 점도는 1,000 cp 내지 50,000 cp 사이인 것을 특징으로 한다, 분자량이 너무 낮고 점도가 낮은 경우 분극입자의 분산을 안정화시키는 역할을 수행하기 어려우며, 분자량이 높고 점도가 너무 높으면 분극입자가 자유로운 브라운 운동을 하기 어려울 수 있다.The liquid dispersion stabilizer is characterized in that the number average molecular weight is between 3,000 and 60,000, and the viscosity is between 1,000 cp and 50,000 cp. When the molecular weight is too low and the viscosity is too low, the role of stabilizing the dispersion of polarized particles is difficult to perform, and if the molecular weight is high and the viscosity is too high, it may be difficult for polarized particles to perform free Brownian motion.
상기 분극입자는 형상 이방성을 지니며, 300nm 이상, 1 마이크로 이하의 크기를 갖고, 전기장 혹은 자기장에 따라 배열할 수 있도록 이온을 포함하거나 극성이 매우 높거나 자성을 띨 수 있으며, 표면에 수소결합이 가능한 N, O, F, S의 원소를 포함하는 것을 특징으로 한다. 분극입자는 전기장이 형성되지 않은 상태에서는 브라운 운동을 하며 가시광선 영역의 빛을 차단하며, 전기장이 형성된 경우 전기장에 평행하게 배열함으로써 가시광선 영역의 빛을 통과시켜 투과율을 조절하게 되므로 형상 이방성을 지녀야 효과적으로 투과율을 조절할 수 있다. 또한 가시광선 영역은 대략 380~750nm의 파장을 가지므로 이의 차단 혹은 투과와 더불어 전기장에 따른 빠른 회전을 위해서 분극입자의 크기는 1 마이크로 이하인 것이 적절하며, 300 nm를 초과하는 경우 가시광선 영역의 빛을 차단하기에 부족하다. 또한 입자의 표면에는 전기음성도가 큰 N, O, F를 지니고 있어서 분산 안정제의 결합부와 수소결합에 의해 단단하게 결합하기 쉽다.The polarized particles have shape anisotropy, have a size of 300 nm or more and 1 micron or less, contain ions to be arranged according to an electric or magnetic field, have a very high polarity or be magnetic, and have hydrogen bonds on their surfaces. Characterized in that it contains the elements of N, O, F, and S possible. Polarized particles perform Brownian motion and block light in the visible ray region when an electric field is not formed, and when an electric field is formed, they are arranged in parallel to the electric field to pass light in the visible ray region and adjust the transmittance. Therefore, they must have shape anisotropy. The transmittance can be effectively controlled. In addition, since the visible light region has a wavelength of approximately 380 to 750 nm, it is appropriate for the size of the polarized particles to be less than 1 micron in order to block or transmit them and to rotate rapidly according to the electric field. is not enough to block In addition, since the surface of the particle has N, O, and F having high electronegativity, it is easy to firmly bond with the bonding portion of the dispersion stabilizer by hydrogen bonding.
상기 액상의 분산안정제의 용해부와 극성 고분자 수지는 분산력에 대한 용해도 파라미터 및 극성력에 대한 용해도 파라미터에서 2를 초과하여 차이나는 것을 특징으로 한다. 액상의 분산안정제의 용해부와 극성 고분자 수지는 분산력에 대한 용해도 파라미터 및 극성력에 대한 용해도 파라미터 2 이하인 경우 분리된 상을 만들기 어려워 분극입자 현탁액의 분리된 액적을 형성하기 곤란하다.It is characterized in that the dissolving part of the liquid dispersion stabilizer and the polar polymer resin differ by more than 2 in the solubility parameter for the dispersing force and the solubility parameter for the polar force. When the solubility parameter for the dispersion force and the solubility parameter for the polar force are 2 or less between the dissolving part of the dispersion stabilizer in the liquid phase and the polar polymer resin, it is difficult to form a separated phase and form separated droplets of the polarized particle suspension.
아울러 상기 분극입자 현탁액을 형성하는 경우, 액상의 분산안정제 외에 분산안정제의 용해부와 상용성이 높거나 용해도 파라미터가 유사한 고비점 가소제 등을 첨가하여 현탁매의 점도를 추가적으로 낮출 수 있는 바, 상기 고비점 가소제로서는 디-2-에틸헥실프탈레이트(di-2-ethylhexyl phthalate), 디이소옥틸프탈레이트(di-isooctyl phthalate), 디카프릴프탈레이트(di-capryl phthalate), 디-n-옥틸프탈레이트(di-n-octyl phthalate), 부틸-벤질프탈레이트(butyl-benzyl phthalate), 디이소헵틸프탈레이트(di-isoheptyl phthalate), 디이소노닐프탈레이트(di-isononyl phthalate), 디이소데실프탈레이트(di-isodecyl phthalate), 디트리데실프탈레이트(di-tridecyl phthalate), 디운데실프탈레이트(di-undecyl phthalate), 디도데실프탈레이트(di-dodecyl phthalate), 디이소데실프탈레이트(di-isododecyl phthalate) 또는 이들의 이소프탈레이트 또는 테레프탈레이트, 또는 트리-2-에틸헥실트리멜리테이트(tri-2-ethylhexyl trimellitate), 디-2-에틸헥실아디페이트(di-2-ethylhexyl adipate), 디이소노닐아디페이트(di-isononyl adipate), 디이소데실아디페이트(di-isodecyl adipate), 디-2-에틸헥실세바케이트(di-2-ethylhexyl sebacate), 디-2-에틸헥실아젤레이트(di-2-ethylhexyl azelate), 에폭시화소이빈오일(epoxidized soy bean oil), 2-에틸헥실에폭시탈레이트(2-ethylhexyl epoxy tallate), 디이소데실테트라히드로-4,5-에폭시프탈레이트(di-isodecyl tetrahydro-4,5-epoxy phthalate), 폴리알킬렌아디페이트(poly(akylene adipates)), 폴리알킬렌세바케이트(poly(alkylene sebacates)) 및 폴리알킬렌아젤레이트(poly(alkylene azelates))로 이루어진 군으로부터 선택된 1종 이상의 것일 수 있다.In addition, in the case of forming the polarized particle suspension, the viscosity of the suspension medium can be further lowered by adding a high boiling point plasticizer that is highly compatible with the dissolving part of the dispersion stabilizer or has a similar solubility parameter, in addition to the liquid dispersion stabilizer.

상기 투과도 가변 필름의 매트릭스(기재)가 되는 고분자 수지는 분산안정제의 용해부에 비하여 상대적으로 높은 극성을 지니고 있어서 분산안정제와의 상용성이 낮은 것을 특징으로 한다.The polymer resin, which is the matrix (substrate) of the variable permeability film, has a relatively high polarity compared to the dissolving portion of the dispersion stabilizer, and thus has low compatibility with the dispersion stabilizer.

On the other hand, if the molecular weight is too large, it is difficult for the reactive functional group to form a sufficient bond, and there is a concern that a large amount of unreacted material may remain.
