It is well known that frost occurs on the surface of automobile glass due to the temperature difference between the outside and inside of the vehicle, or condensation occurs when water droplets form on the surface of the glass bulkhead due to the temperature difference between the slope inside and outside of the indoor ski resort.
As a means for removing such frost and preventing condensation, a heating glass having a hot wire has been applied.
The heating glass uses a concept of attaching a hot wire sheet to the glass surface or directly forming a hot wire on the glass surface and applying heat to both terminals of the hot wire to generate heat from the hot wire, thereby raising the temperature of the glass surface. Mostly.
Existing transparent heating glass is made of transparent conductive materials such as ITO or Ag thin film in consideration of the fact that heating glass for automobile or building needs to generate heat smoothly and maintain low resistance and transparency in order to secure a good external view. After forming a transparent surface heating layer by the sputtering process, a method of manufacturing an electrode was used, but the heating glass according to this method had a problem that it was difficult to be driven at a low voltage of 40V or less due to high sheet resistance, and also due to the characteristics of the surface electrode. There was a limiting problem in implementing a large area.

However, by dispersing the carbon nanotubes in a solvent and forming a dense layer of nanomaterials to form a conductive layer using carbon nanotubes alone, the control of electrical conductivity is not easy and problems such as a decrease in adhesion to the substrate are encountered. There is a disadvantage in that the durability of the heater is inferior.
In the case of the technique disclosed in the "heating element using carbon nanotubes," a carbon substrate is electrically connected to a power source while being electrically connected to a substrate having heat resistance, a carbon nanotube coating layer formed on at least one surface of the heat resistant substrate, and a carbon nanotube coating layer. It is characterized in that it comprises a pair of electrodes to induce heat generation of the nanotube coating layer.

Hereinafter, the present invention will be described in more detail.
As is well known, carbon nanotubes are a kind of carbon allotrope made of carbon, and have a cylindrical tube shape in which one carbon is bonded to another carbon atom and hexagonal honeycomb shape. The diameter is 1-100 nm level.
These carbon nanotubes possess all of excellent electrical, thermal, chemical, mechanical and structural properties, which are emerging as a new core material of the next generation, and can be used as heating elements by acting as resistors when applying electricity.
In particular, as the synthesis of carbon nanotube yarns becomes possible, a conventional method of forming a carbon nanotube thin film transparent heater which has been manufactured by coating process after dispersing a metal thin film transparent heater, ITO transparent heater using a vacuum deposition method, and so on. Unlike the present invention, a transparent heater can be manufactured using a method of attaching a yarn to a transparent substrate.
Conventionally, a carbon nanotube heating element is formed by coating a carbon nanotube dispersion in a solution state as described above, but most of them may cause a temperature difference between substrates due to thickness variation during coating, and a binder used in manufacturing a solution phase. Although there was a limitation in realizing the properties of the carbon nanotubes themselves due to the influence of the dispersing agent, the carbon nanotube yarns used in the present invention are in the form of a thread composed of several layers of carbon nanotubes, and have excellent electrical transfer properties. Also excellent in the heat generation characteristics, and by adjusting the thickness of the yarn and the formation interval of the yarn constituting the heating line can be freely adjusted the permeability and sheet resistance of the transparent heater.
In addition, by using a yarn having a high purity and a predetermined thickness consisting of only carbon nanotubes, it is possible to obtain a transparent heating element having a uniform temperature distribution as a whole, that is, between the lines forming the thickness or pattern of the carbon nanotube yarns There is an advantage that can be accurately implemented by adjusting the interval of.
In addition, the yarn having a certain thickness of high purity made of carbon nanotubes only has excellent thermal conductivity characteristics, unlike the general heating element is constantly rising temperature has the advantage of maintaining a constant temperature at the same voltage.
Herein, the transparent heater using the carbon nanotube yarn according to the present invention will be described in detail.

In this case, the carbon nanotube yarn thickness can be controlled by controlling the pulling force and pulling force of the yarn from the forest in the manufacturing process of the yarn, the width of the yarn in the width direction of the yarn is 1 ~ 100μm or less to maintain transparency as a heating element The reason is that if the thickness is less than 1μm, it is difficult to manufacture a long length yarn because of stability in the manufacturing process of the yarn, whereas if the yarn is manufactured to a thickness of 100μm or more, the thickness of the yarn is visually confirmed and the transparency It has a downside.
Next, the carbon nanotube yarns prepared as described above are aligned and fixed on the upper layer of the
That is, the
At this time, the
On the contrary, when the thickness of the carbon nanotube yarns is made thick and arranged at wide intervals, heating lines made of carbon nanotube yarns appear on the transparent substrate, and when the thick yarns are arranged at narrow intervals, the overall permeability is reduced.
Therefore, the thickness and formation interval of the carbon nanotube yarns should be adjusted in consideration of the permeability and heat generation characteristics of the place of use.
In addition, when single-walled carbon nanotubes (SWNT), double-walled carbon nanotubes (DWNT), and multi-walled carbon nanotubes (MWNT) are made of yarn, their resistance values are different. .
Meanwhile, the binder material is coated on the
The binder improves the adhesion of the carbon nanotube yarns to the transparent substrate, and serves to improve chemical stability and durability, and the binder material is preferably subjected to a separate solidification process.
Optionally, as another method of fixing the carbon nanotube yarns of the present invention to a transparent substrate, the carbon nanotube yarn strands are laminated in advance in a binder without first coating a binder on the transparent substrate as described above, and then the desired It is also possible to use a method of adhering according to the heating pattern and fixing by UV or heat treatment.
The transparent heater using the carbon nanotube yarn according to the present invention, as shown in Figure 2b, to form a heating line consisting of carbon nanotube yarn on the metal thin film, ITO transparent thin film, carbon nanotube thin film made of a conventional
Next, electrode terminal layers 16 are formed at both ends of the
The
Finally, a transparent film such as film or glass is laminated on the surface of the
Hereinafter, the transparent heater using the carbon nanotube yarn of the present invention will be described in more detail as an example.
Example
Using a carbon nanotube yarn manufacturing apparatus, carbon nanotube yarns were prepared from a multi-walled carbon nanotube forest, and the thickness of the carbon nanotube yarns was set to 5, 10, and 20 μm to prepare transparent heaters as follows.
Glass was used as a transparent substrate, and one surface of the glass substrate was coated with an epoxy binder, and each carbon nanotube yarns having a thickness of 5, 10, and 20 μm were arranged at 0.5 mm and 1 mm intervals.
Subsequently, the binder was solidified by thermosetting, so that the carbon nanotube yarns were stably fixed onto the glass, which is a transparent substrate, as a conductive heating wire.
Next, electrode terminal layers were formed on both sides of the glass substrate on which the conductive heating lines were arranged so as to be perpendicular to the array direction of the yarns, and lead wires for applying current to the electrode terminal layers were connected.
In addition, in order to protect the conductive heating line, a transparent film was attached on the glass which is a transparent substrate.
Test Example
The transmittance of the transparent heater prepared according to the embodiment was measured through UV, and the maximum temperature was measured to confirm the exothermic state at the applied voltage of 20 V. The results are shown in Table 1, and the initial temperature generated was It was confirmed that the change in temperature over time for 10 hours, the result is as shown in FIG.
As shown in Table 1 above, it can be seen that the heat generation amount can be adjusted according to the thickness and arrangement interval of the carbon nanotube yarns, and the thicker the yarn thickness, the higher the heat generation amount.
In addition, looking at the yarn permeability of the transparent heater manufactured according to the embodiment, it was found that more than 80% in both cases arranged at 0.5mm and 1mm intervals, as shown in Figure 4, the conductive heating wire is maintained for a long time at the initial temperature Could.
