Abstract

According to the present invention, a heating membrane includes: a membrane (M) consisting of carbon nanofibers; an electrode wire (W) arranged on the membrane (M); and a cell (C) configured to apply a voltage to the electrode wire (W). The heating membrane has excellent flexibility and can effectively prevent a loss of heating function due to a short circuit caused by folding, thereby being particularly suitable to be applied to a three-dimensional structure such as clothing or the like. Furthermore, the heating membrane allows its temperature to be increased even when a low voltage below 10 V is applied thereto because the heating membrane includes the membrane consisting of carbon nanofibers, thereby enabling long-term heat insulation even with a small-capacity cell. As a result, the heating membrane can be applied to sports clothes or industrial purposes where heat insulation is required by being attached to various clothing products or three-dimensional structures.

Description

유연성이 우수한 발열 멤브레인{Heat generating membranes with excellent fiexibility}[0001] Heat-generating membranes with excellent flexibility [

본 발명은 유연성이 우수한 발열 멤브레인에 관한 것으로서, 구체적으로는 탄소나노섬유로 구성된 멤브레인에 전극선과 전지가 각각 배열/연결되어 10V 이하의 낮은 전압으로도 온도상승이 가능함과 동시에 유연성이 뛰어나 의류 등의 3차원 구조물에 적용시에도 접힘현상 등으로 단락이 안생겨 발열 기능을 계속 유지할 수 있는 발열 멤브레인에 관한 것이다.
More particularly, the present invention relates to an exothermic membrane excellent in flexibility, and more particularly, to a membrane made of carbon nanofibers, in which an electrode line and a battery are arranged and connected to each other so that the temperature can be raised even at a low voltage of 10 V or less, The present invention relates to a heat-generating membrane capable of continuously maintaining a heat-generating function due to a short-circuit due to a folding phenomenon even when applied to a three-dimensional structure.

면상 발열체에 대한 종래기술로서 대한민국 공개실용신안 제20-2011-0004213호 등에서는 통상적인 직물 또는 부직포 상에 카본 페이스트를 코팅한 후 여기에 전극선과 전기를 각각 배열 / 연결시킨 종래의 면상발열체를 제안하고 있다.As a conventional technique for a planar heating element, Korean Utility Model Publication No. 20-2011-0004213 and the like propose a conventional planar heating element in which a carbon paste is coated on a common woven fabric or nonwoven fabric, and electrode wires and electricity are respectively arranged and connected to the carbon paste. .

그러나, 상기와 같이 직물 또는 부직포 상에 카본 페이스트를 코팅하는 경우 코팅 직물 또는 코팅 부직포는 유연성이 현저하게 떨어진다. 그로 인해 의류 등과 같은 3차원 구조물에 상기 종래의 면상 발열체를 적용할 경우, 유연성이 부족하여 접힘현상 등에 의한 단락이 발생되어 발열 기능이 중단되는 문제가 있었다.However, when the carbon paste is coated on the woven fabric or the nonwoven fabric as described above, the coated fabric or the coated nonwoven fabric has a considerably reduced flexibility. Therefore, when the conventional planar heating element is applied to a three-dimensional structure such as clothing, flexibility is not sufficient and a short circuit due to a folding phenomenon occurs, thereby causing a problem that the heating function is interrupted.

또한, 종래의 면상 발열체의 경우에는 온도 상승 효과를 얻기 위해서 높은 전압을 부여해야하고, 그로 인해 전지 수명이 단축되는 문제도 있었다.
In addition, in the case of the conventional surface heating element, a high voltage is required to obtain a temperature raising effect, thereby shortening the life of the battery.

본 발명의 과제는 유연성이 우수하여 의류 등과 같은 3차원 구조물에 적용시에도 접힘현상으로 인한 단락으로 발열기능이 중단되는 것을 효과적으로 방지할 수 있는 발열 멤브레인을 제공하는 것이다.The object of the present invention is to provide a heat-resistant membrane which is excellent in flexibility and can effectively prevent a heat-generating function from being interrupted due to a short circuit due to a folding phenomenon even when applied to a three-dimensional structure such as clothing.

본 발명의 또 다른 과제는 10V이하의 낮은 전압을 인가시에도 발열 기능이 발현될 수 있어서 소용량 전지로도 장시간 사용이 가능한 발열 멤브레인을 제공하는 것이다.
Another object of the present invention is to provide a heat-generating membrane which can be used even when a small capacity battery is used for a long time because a heat generating function can be exhibited even when a low voltage of 10 V or less is applied.

이와 같은 과제를 달성하기 위해서, 본 발명에서는 탄소나노섬유로 구성된 멤브레인(M)을 발열 본체로 사용하는 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that a membrane M composed of carbon nanofibers is used as a heating body.

구체적으로, 본 발명은 탄소나노섬유로 구성된 멤브레인(M) 상에 전극선(W)을 일정 패턴 / 간격으로 형성시킨 후 상기 전극선(W)에 전지(C)를 한다.
Specifically, the present invention forms the electrode lines W in a predetermined pattern / interval on the membrane M composed of carbon nanofibers, and then places the cells C on the electrode lines W.

본 발명의 발명 멤브레인은 유연성이 우수하여 접힘 현상으로 인한 단락으로 발열기능이 상실되는 것을 효과적으로 방지할 수 있다.The membrane of the present invention is excellent in flexibility and can effectively prevent a heat-generating function from being lost due to a short circuit due to a folding phenomenon.

그로 인해 본 발명의 발열 멤브레인은 의류 등과 같은 3차원 구조물에 적응하는데 특히 유리하다.As a result, the heat-generating membrane of the present invention is particularly advantageous in adapting to a three-dimensional structure such as clothing.

또한, 본 발명의 멤브레인은 탄소나노섬유로 구성된 멤브레인을 포함하기 때문에 10V 이하의 낮은 전압을 가하여 온도 상승이 가능하므로 소용량 전지로도 장시간 보온이 가능하고, 그로 인해 각종 의류제품 또는 3차원 구조물에 부착하여 보온이 필요한 스포츠 의류나 산업용 용도로 적용될 수 있다.Since the membrane of the present invention includes a membrane composed of carbon nanofibers, the temperature can be raised by applying a low voltage of 10 V or less, so that it is possible to maintain a long time with a small capacity battery, And can be applied to sportswear or industrial applications requiring heat insulation.

Polyacrylonitrile (product of Aldrich) having a weight average molecular weight (Mw) of 150,000 was dissolved in dimethylformamide as a solvent to prepare a spinning dope having a solid content of 9 wt% and a viscosity of 477 centipoise. The tube was rotated at a rotation speed of 2000 rpm and a high voltage of 35 kV was applied to the tube. The collector was rotated at 1000 m / min through electrospinning.
