본 발명을 설명하기 위하여 제시되는 도 1은 본 발명의 제1 실시예에 따른 복합필름의 단면도로서, SPD 스마트 필름(10)을 중앙에 배치하고, 상기 SPD 스마트 필름(10) 양측 외측면 각각에 접착시킨 감압 접착제(20) 외측면 각각에 접착시킨 폴리에스터 필름(30)을 포함하여 구성하되, 상기 감압 접착제(20) 내측면과 SPD 스마트 필름(10) 양측 외측면 및 감압 접착제(20) 외측면과 폴리에스터 필름(30) 내측면 사이의 기포를 오토클레이브를 이용하여 제거하도록 하여 복합필름(100) 및 그 제조방법을 제공한다.1 presented to explain the present invention is a cross-sectional view of a composite film according to a first embodiment of the present invention, in which the SPD smart film 10 is placed in the center, and the SPD smart film 10 Consisting of including a polyester film 30 bonded to each of the outer surfaces of the bonded pressure-sensitive adhesive 20, but the pressure-sensitive adhesive 20 inner side and the SPD smart film 10 both outer sides and the pressure-sensitive adhesive 20, etc. A composite film 100 and a method for manufacturing the same are provided by removing air bubbles between the side surface and the inner side of the polyester film 30 using an autoclave.

상기에서, SPD 스마트 필름(10)은 광 밸브(light valve) 현탁액의 방울들이 분산분포되어 있는 가교 결합된 폴리머 매트릭스를 포함하는 광-변조 유닛 필름으로서, 자외선-가교 결합성 액체 올리고머나 폴리머를 상기 광 밸브 현탁액과 혼합하여 자외선 차단을 수행하게 하여 복합필름(100)의 손상을 방지하게 할 수 있다.In the above, the SPD smart film 10 is a light-modulation unit film comprising a crosslinked polymer matrix in which droplets of a light valve suspension are dispersed and distributed, and the UV-crosslinkable liquid oligomer or polymer is described above. It is possible to prevent damage to the composite film 100 by mixing with the light valve suspension to block UV rays.

또한, 상기 SPD 스마트 필름(10)이 활성 상태에 있을 때 상기 SPD 스마트 필름(10)의 흐릿함 및 광 산란을 감소 또는 제거할 수 있도록 할 수 있다.In addition, when the SPD smart film 10 is in an active state, blurring and light scattering of the SPD smart film 10 may be reduced or eliminated.

그리고, 본 발명에서 제시되는 복합필름(100)의 전체 두께는 0.5mm 이하로 제시하는 것이 바람직하고, 예컨대 감압 접착제(20)의 두께를 0.02mm ~ 0.023mm로 하고, 폴리에스터 필름(30)의 두께는 0.05mm로 하되, SPD 스마트 필름(10)의 두께를 0.36mm이하로 제시하는 것이 바람직하다.In addition, the total thickness of the composite film 100 presented in the present invention is preferably 0.5 mm or less, for example, the thickness of the pressure-sensitive adhesive 20 is 0.02 mm to 0.023 mm, and the polyester film 30 is The thickness is 0.05mm, but it is preferable to present the thickness of the SPD smart film 10 to 0.36mm or less.

또한, 본 발명은 SPD 스마트 필름(10) 양측에 접착하는 폴리에스터 필름(30) 대신에 초박판 강화유리 또는 폴리이미드 필름 또는 TPU 필름을 대체하여 사용할 수 있고, 상기 폴리에스터 필름(30) 외측면에 윈도우 글라스 점착을 위한 점착제가형성될 수 있다.In addition, the present invention can be used in place of the polyester film 30 adhered to both sides of the SPD smart film 10, an ultra-thin tempered glass or a polyimide film or a TPU film, and the outer surface of the polyester film 30 A pressure-sensitive adhesive for adhering to the window glass may be formed.

이와 같은 구성을 통하여 얻어진 복합필름(100)을 차량의 윈도우 글라스에 부착시킬 경우에는 약간의 물을 윈도우 글라스에 살포한 후 복합필름(100)을 윈도우 글라스에 면접시킨 다음 고무 롤러(Squeegee)를 이용하여 적정압력을 가하면 수월하게 기포가 제거된 상태로 강한 부착이 이루어진다. 따라서, 상기 폴리에스터 필름(30) 외측면에 형성한 윈도우 글라스 점착을 위한 점착제에 의하여 점착이 이루어지므로 수분 이외의 별도의 접착을 위한 접착제가 필요없게 된다.When attaching the composite film 100 obtained through this configuration to the window glass of a vehicle, spray a little water on the window glass, and then interview the composite film 100 to the window glass, and then use a squeegee. Thus, when appropriate pressure is applied, strong adhesion is achieved with the air bubbles removed easily. Therefore, since adhesion is made by the adhesive for adhesion to the window glass formed on the outer surface of the polyester film 30, an adhesive for adhesion other than moisture is not required.

도 2는 본 발명의 제2 실시예에 따른 복합필름(100)의 단면도로서, SPD 스마트 필름(10) 양측 외측면 각각과 폴리에스터 필름(30) 사이에 전극(40)을 부설하여 윈도우 글라스에 설치한 cds 등과 같은 조도센서(50) 또는 온도센서의 센싱에 따라 투명도가 자동조절되도록 제공할 수 있다.2 is a cross-sectional view of a composite film 100 according to a second embodiment of the present invention, by placing an electrode 40 between each of the outer surfaces of both sides of the SPD smart film 10 and the polyester film 30 to the window glass. Transparency may be automatically adjusted according to the sensing of an illuminance sensor 50 or a temperature sensor such as an installed cds.

즉, 조도센서(50)를 윈도우 글라스에 설치하여 윈도우 글라스 외부 환경 즉, 밝기 정도에 따라 복합필름(100)의 투명도를 자동 조절하게 할 수 있다.That is, by installing the illuminance sensor 50 on the window glass, it is possible to automatically adjust the transparency of the composite film 100 according to the external environment of the window glass, that is, the degree of brightness.

제시하는 도 4는 본 발명에 따른 복합필름(100)의 투명도를 자동조절하도록 하는 회로 블럭도로서, 조도센서(50)에 따른 외부환경의 밝기에 대응하는 센싱 신호를 제어하는 마이크로 프로세서 유니트로 구성하는 제어 회로부(60)에 의하여 SPD 스마트 필름(10)의 전극(40)에 연결된 온/오프 스위치(70)를 제어하여 윈도우 글라스의 투명도를 자동조절하게 할 수 있고, 상기 제어 회로부(60)에 연결한 무선 송신부(80)와 복합필름(100)에 설치한 무선 수신부(90)에 의하여 무선으로 복합필름(100)의 투명도를 자동조절 가능하게 할 수도 있다.4 is a circuit block diagram for automatically adjusting the transparency of the multilayer film 100 according to the present invention, and is composed of a microprocessor unit that controls a sensing signal corresponding to the brightness of the external environment according to the illuminance sensor 50 The on/off switch 70 connected to the electrode 40 of the SPD smart film 10 can be controlled by the control circuit unit 60 to automatically adjust the transparency of the window glass, and the control circuit unit 60 It is also possible to automatically adjust the transparency of the multiple film 100 by wireless by the connected wireless transmission unit 80 and the wireless reception unit 90 installed on the multiple film 100.

상기에서 무선 송/수신은 블루투스 방식 등 근거리 무선통신이면 바람직하다.In the above, the wireless transmission/reception is preferably a short-range wireless communication such as a Bluetooth method.

그리고, 상기 전극(40)은 전기전도성 금속산화물 및 기타 코팅만을 의미하는 것이 아니라, 실리콘 재료상에 유전체 코팅을 가지는 전극이면 바람직하다.In addition, the electrode 40 does not mean only an electrically conductive metal oxide and other coatings, but is preferably an electrode having a dielectric coating on a silicon material.

또한, 상기 전극(40)에 인가되는 전원은 승압 트랜스 및 인버터를 통하여 교류전류 공급이 가능하게 할 수 있다.In addition, the power applied to the electrode 40 may enable AC current to be supplied through a booster transformer and an inverter.

이와 같은 구성의 본 발명은 도 3의 (a)와 같이 전극(40)에 연결된 온/오프 스위치(70)가 오프된 경우에는 SPD 스마트 필름(10) 내부의 현탁액 방울 내의 분산된 입자들이 브라운 운동으로 무작위에 위치하고, 이에 따라 입자들이 빛을 흡수하게 되므로 외부의 빛이 복합필름(100)을 통과하지 못하게 되고, 도 3의 (b)와 같이 전극(40)에 연결된 온/오프 스위치(70)가 온된 경우에는 입자들이 정렬되면서 외부의 빛이 복합필름(100)을 통과하게 되므로 광 산란 및 흐릿함을 감소 또는 제거할 수 있다.In the present invention of this configuration, when the on/off switch 70 connected to the electrode 40 is turned off as shown in FIG. 3 (a), the dispersed particles in the droplets of the suspension inside the SPD smart film 10 move brown. As a result, the particles are randomly located, and thus the particles absorb light, so that external light cannot pass through the composite film 100, and the on/off switch 70 connected to the electrode 40 as shown in FIG. 3(b). When turned on, since the particles are aligned and external light passes through the composite film 100, light scattering and blurring can be reduced or eliminated.

따라서, 본 발명에 따른 복합필름(100)에 의한 투명도 조절을 위한 반응속도가 신속하게 이루어지게 되고, 조도센서(50)를 이용하여 외부환경에 따른 투명도의 자동조절이 가능하게 되므로, 예컨대 터널을 진입하거나 지하 주자공간으로 차량이 진입할 경우 윈도우 글라스의 투명도를 신속하게 높여 안전한 시야 확보가 이루어져 안전사고 유발을 방지하고, 조도센서(50) 이외의 온도센서를 이용하여 운전자의 자외선 차단은 물론 장거리 운전 시 자외선 노출로 인한 피로감을 줄이기 위하여 해가 비추는 측의 창문의 투명도를 어둡게 자동조절할 수 있다.Therefore, the reaction speed for adjusting the transparency by the composite film 100 according to the present invention is quickly achieved, and the automatic adjustment of the transparency according to the external environment is possible using the illuminance sensor 50, for example, a tunnel When a vehicle enters or enters an underground runner space, the transparency of the window glass is quickly increased to ensure a safe field of view to prevent safety accidents, and a temperature sensor other than the illuminance sensor 50 prevents the driver from UV rays and long distance In order to reduce fatigue caused by UV exposure while driving, the transparency of the window on the side of the sun can be automatically adjusted to darken.

상기에서는 본 발명의 실시예를 참조하여 설명하였지만, 해당 기술 분야의 통상의 지식을 가진자는 하기의 청구범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다. 그리고, 이러한 수정과 변경에 관계된 차이점들을 첨부된 청구범위에서 규정하는 본 발명의 범위에 포함되는 것으로 해석되어야 할 것이다.Although the above has been described with reference to the embodiments of the present invention, those skilled in the art will variously modify and change the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims.
