본 발명은 연속식 상압플라즈마 장치를 이용한 탄소섬유의 표면처리방법에 관한 것으로, 더욱 상세하게는 탄소섬유의 표면처리방법에 있어서, 상압플라즈마 장치를 사용하여 표면처리를 하되, 플라즈마 처리시의 전력량, 처리시간, 가스혼합비율, 전극과 탄소섬유와의 거리 등을 최적화 하여 계면결합력이 우수한 탄소섬유를 제조할 수 있는 탄소섬유의 표면처리방법에 관한 것이다. The present invention relates to a surface treatment method of carbon fibers using a continuous atmospheric plasma apparatus, and more particularly, in the surface treatment method of carbon fibers, the surface treatment using an atmospheric pressure plasma apparatus, the amount of power during plasma treatment, The present invention relates to a carbon fiber surface treatment method capable of producing carbon fibers having excellent interfacial bonding force by optimizing treatment time, gas mixing ratio, distance between electrode and carbon fiber, and the like.
우주항공산업, 핵, 일반기술 및 고기술 분야와 베어링, 기어, 그리고 자동차 동체 등과 같은 운송 분야에서 고분자 복합재료가 많이 이용되고 있다.Polymer composites are widely used in the aerospace, nuclear, general and high technology sectors as well as in the transportation sectors such as bearings, gears, and automotive fuselage.
고분자 복합재료란, 고분자, 금속, 세라믹 및 탄소재료 등에서 얻은 하나 또는 그 이상의 강화제와 연속상인 고분자 수지 결합재 또는 기지로 구성된 시스템을 의미한다.The polymer composite material means a system composed of a polymer resin binder or matrix in continuous phase with one or more reinforcing agents obtained from polymers, metals, ceramics and carbon materials.
이와 같은 시스템에서 강화제는 흔히 섬유상과 충전상으로 나눌 수 있으며, 현재 선진 고분자 복합재료에서는 탄소섬유가 주종을 이루고 있다.In these systems, reinforcing agents are often divided into fibrous and packed phases, and carbon fiber is dominated by advanced polymer composites.
탄소섬유는 내열성, 화학적 안정성, 전기전도성, 유연성 등 다양하게 우수한 특징을 가지고 있어 여러 산업분야에서 폭넓은 응용이 가능하고, 특히 우수한 계면 결합력을 가지는 탄소섬유는 고분자 복합재료에 주재료로 사용될 만한 물질로 연구되고 있다.Carbon fiber has various characteristics such as heat resistance, chemical stability, electrical conductivity, and flexibility, so that it can be widely applied in various industrial fields. Especially, carbon fiber having excellent interfacial bonding strength can be used as a main material for polymer composite materials. Is being studied.
탄소섬유의 계면결합력을 향상시키기 위한 탄소섬유의 표면처리방법은 기상산화, 액상산화, 전기화학적 산화 등이 있다. 액체를 이용한 산화법과 전기 화학적 처리방법은 화학약품에 의한 처리 후 발생하는 폐수와 장시간의 전기화학적 처리 및 관리비용이 필요하다는 단점이 있기 때문에 공정이 간단하고, 부산물이 거의 없으며, 섬유 자체 물성의 손상이 가장 적은 기상산화(플라즈마)법이 최근 주로 사용된다.Surface treatment methods of carbon fibers to improve the interfacial bonding strength of the carbon fibers include gas phase oxidation, liquid phase oxidation, electrochemical oxidation. Oxidation and electrochemical treatment using liquids have the disadvantage of requiring wastewater generated after chemical treatment and long-term electrochemical treatment and maintenance costs, so the process is simple, there are few by-products, and the property of fiber itself is damaged. This least vapor phase oxidation (plasma) method is mainly used recently.
그러나, 온도, 압력 등에 의한 플라즈마 발생의 불안정한 조건들로 인해 연속식 플라즈마 장치를 구성하는데는 어려움이 있다.However, there are difficulties in constructing a continuous plasma apparatus due to unstable conditions of plasma generation due to temperature, pressure, and the like.
이에 본 발명자들은 탄소섬유의 계면결합력을 향상시킬 수 있는 상압플라즈마 장치를 이용한 탄소섬유의 표면처리 방법을 최적화 하고자 예의 검토한 결과, 전력의 세기(전력량), 가스 비율, 처리시간, 전극과 탄소섬유 시편 간의 거리가 최적의 조건으로 고정된 연속식 상압플라즈마 장치로부터 발생되는 상압플라즈마를 이용하여 탄소섬유 표면을 처리함에 따라 탄소섬유의 접착력이 개선되는 것을 확인하고, 본 발명을 완성하였다. Accordingly, the present inventors have diligently studied to optimize the surface treatment method of the carbon fiber using the atmospheric pressure plasma device that can improve the interfacial bonding force of the carbon fiber, the power intensity (power amount), gas ratio, treatment time, electrode and carbon fiber It was confirmed that the adhesive force of the carbon fiber is improved by treating the surface of the carbon fiber by using the atmospheric pressure plasma generated from the continuous atmospheric plasma device in which the distance between the specimens is fixed at the optimum condition, and completed the present invention.
결국, 본 발명의 주된 목적은 연속식 상압플라즈마장치를 이용한 탄소섬유의 표면처리방법을 제공하는데 있다. After all, the main object of the present invention is to provide a method for surface treatment of carbon fibers using a continuous atmospheric plasma apparatus.
상기 목적을 달성하기 위하여, 본 발명은 연속식 상압플라즈마장치를 이용한 탄소섬유의 표면처리방법을 제공한다.In order to achieve the above object, the present invention provides a carbon fiber surface treatment method using a continuous atmospheric plasma apparatus.
본 발명은 또한 상기 방법에 따라 표면처리된 탄소섬유를 제공한다.The present invention also provides a carbon fiber surface treated according to the above method.
본 발명은 연속식 상압플라즈마장치를 이용하여 탄소섬유의 표면을 처리하는 방법을 제공하는 효과가 있다.The present invention has the effect of providing a method for treating the surface of the carbon fiber using a continuous atmospheric plasma device.
본 발명에 따른 연속식 상압플라즈마장치를 이용한 탄소섬유의 표면처리방법은 플라즈마가 탄소섬유에 주는 영향력이 좋은 최적의 조건을 사용함으로써 높은 계면결합력을 갖는 탄소섬유를 제조할 수 있다. The surface treatment method of the carbon fiber using the continuous atmospheric pressure plasma apparatus according to the present invention can produce a carbon fiber having a high interfacial bonding force by using the optimum conditions that the plasma has a high impact on the carbon fiber.
또한, 본 발명에 따른 방법은 진공이 필요 없는 상온, 상압에서 실시하므로 공정의 안정성이 부여될 뿐만 아니라, 상압플라즈마 처리를 연속적으로 수행함으로써 공정 시간을 단축하고 제조원가를 낮출 수 있다. In addition, the method according to the present invention is carried out at room temperature and atmospheric pressure, which does not require vacuum, and thus not only the stability of the process is provided but also the process time can be shortened and the manufacturing cost can be lowered by continuously performing the atmospheric pressure plasma treatment.
이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명은 연속식 상압플라즈마장치를 이용한 탄소섬유의 표면처리방법을 제공한다. The present invention provides a method for treating carbon fibers using a continuous atmospheric plasma apparatus.
구체적으로, 본 발명은 플라즈마 발생에 영향을 주는 인자들을 포함하여 화 학적 반응을 이용한 플라즈마 발생에 탄소섬유를 노출시키는 것을 포함하는 연속식 상압플라즈마장치를 이용한 탄소섬유의 표면처리방법을 제공한다.Specifically, the present invention provides a method for surface treatment of carbon fibers using a continuous atmospheric pressure plasma apparatus including exposing the carbon fibers to plasma generation using a chemical reaction, including factors affecting plasma generation.
본 발명에 있어서, 상기 탄소섬유는 카본 블랙, 카본 섬유 또는 풀러렌을 포함할 수 있다.In the present invention, the carbon fiber may include carbon black, carbon fiber or fullerene.
또한, 플라즈마 처리시의 상압플라즈마 세기(전력량)는 10 내지 600 W인 것이 바람직하다. 상압플라즈마의 세기가 10 W 미만에서는 플라즈마의 발생량이 너무 적어 섬유 표면에 영향을 주는데 적합하지 못하고, 600 W를 초과하는 경우에는 섬유 표면에 손상을 주며 섬유가 끊어지고 타버릴 우려가 있어 바람직하지 못하다. Moreover, it is preferable that the atmospheric pressure plasma intensity (electric power amount) at the time of plasma processing is 10-600W. If the intensity of the atmospheric pressure plasma is less than 10 W, the amount of plasma generated is too low to be suitable for affecting the fiber surface, and if it exceeds 600 W, it is not preferable because the fiber surface may be damaged and the fiber may be broken and burned. .
또한, 플라즈마 처리시의 상압플라즈마 처리 시간은 1 내지 600초인 것이 바람직하다. 1초 미만에서는 화학적 반응이 일어나기 어려우며, 600초를 초과하면 섬유 표면이 손상되어 섬유 자체가 타버리는 현상이 발생되기 때문이다.Moreover, it is preferable that the atmospheric pressure plasma processing time at the time of plasma processing is 1 to 600 second. This is because chemical reactions are less likely to occur in less than 1 second, and in excess of 600 seconds, the surface of the fiber is damaged and the fiber itself burns out.
또한, 플라즈마 처리시 분위기는 비활성 가스와 활성가스가 혼합된 혼합가스인 것이 바람직하고, 더욱 바람직하게는 헬륨가스와 산소가스가 혼합된 분위기에서 처리되는 것이 좋고, 가장 바람직하게는 헬륨가스 80 내지 99.99% 및 산소가스 0.01 내지 20%의 비율로 이루어지는 혼합가스 분위기에서 처리되는 것이 좋다. 산소가스의 비율이 0.01% 미만에서는 탄소섬유 표면에 산소를 함유하는 극성 관능기가 도입되는데 산소 가스가 영향을 주기 어려우며, 20%를 초과하면 산소가스의 양이 플라즈마 발생을 불안정하게 하기 때문에 바람직하지 않다.In addition, it is preferable that the atmosphere during the plasma treatment is a mixed gas in which an inert gas and an active gas are mixed, and more preferably, it is treated in an atmosphere in which helium gas and oxygen gas are mixed, and most preferably helium gas 80 to 99.99. It is preferred to be treated in a mixed gas atmosphere composed of% and oxygen gas at a ratio of 0.01 to 20%. If the ratio of oxygen gas is less than 0.01%, the polar functional group containing oxygen is introduced to the surface of the carbon fiber, but it is difficult to influence the oxygen gas, and if it exceeds 20%, the amount of oxygen gas is undesirably unstable to generate plasma. .
또한, 플라즈마 처리시 전극과 탄소섬유와의 거리는 1 내지 50 ㎜인 것이 바람직하다. 탄소섬유와 전극간의 거리가 1 ㎜ 보다 짧을 경우, 처리가 어렵고 반대 로 50 ㎜를 넘을 경우에는 플라즈마의 세기가 약해져서 탄소섬유에 영향을 주기 어렵다.In the plasma treatment, the distance between the electrode and the carbon fiber is preferably 1 to 50 mm. When the distance between the carbon fiber and the electrode is shorter than 1 mm, the treatment is difficult. On the contrary, when the distance between the carbon fiber and the electrode is larger than 50 mm, the strength of the plasma is weakened, and thus it is difficult to affect the carbon fiber.
또한, 플라즈마 처리시의 주파수는 플라즈마를 안정적으로 형성시키는 13.56 ㎒인 것이 바람직하며, 캐리어 가스의 주입량은 매스 플로우 컨트롤러(Mass Flow Controller, MFC)를 사용하여 일정하게 유지시키는 것이 바람직하다. In addition, the frequency during the plasma treatment is preferably 13.56 MHz to stably form the plasma, and the injection amount of the carrier gas is preferably kept constant using a mass flow controller (MFC).
본 발명은 또한 상기 방법에 따라 표면처리된 탄소섬유를 제공한다.The present invention also provides a carbon fiber surface treated according to the above method.
