Abstract
The present invention relates to an iron-nickel (Fe-Ni) alloy foil, and more particularly, to an iron-nickel (Fe-Ni) alloy foil suitable for an Organic Light Emitting Diode (OLED) material and a method for manufacturing the same.
Description
Technical Field
The present invention relates to an iron-nickel (Fe-Ni) alloy foil, and more particularly, to an iron-nickel (Fe-Ni) alloy foil suitable for an Organic Light Emitting Diode (OLED) material and a method for manufacturing the same.
Background
Organic Light Emitting Diodes (OLEDs) are attracting attention in the current Display device market as a next-generation Display device capable of replacing LCDs (Liquid Crystal displays).
The OLED can emit light and color by itself, adjust the light quantity, and has the advantages of low power consumption, high response speed and almost no residual image. In addition, the color sense is vivid and bright, and the visual field angle is wide.
Due to such advantages, the OLED display industry is recently working on the automobile, mobile device, and TV markets.
Full-color (Fullcolor) elements composed of RGB Sub-pixels (RGB Sub-pixels) used in the manufacture of OLED display devices are manufactured in a high-temperature evaporation apparatus. The vapor deposition apparatus is composed of a substrate, a vapor deposition mask, a frame, and the like, and since the vapor deposition process is performed at a high temperature, a positional difference occurs due to a dimensional change caused by a thermal expansion coefficient under the influence of temperature. Therefore, there is a problem that the position and dimensional accuracy of the deposition material adhering to the substrate are low. Therefore, in order to accurately position the mask, prevent thermal expansion, and satisfy the precision of the mask and the substrate, it is necessary to select a mask and a frame material having the same level of thermal expansion coefficient as the substrate.
On the other hand, invar (Fe-36% Ni) of an iron-nickel (Fe-Ni) alloy system is mainly used as a material of the vapor deposition mask. The invar alloy manufactured through a conventional rolling process has a problem in that the characteristics of the element are lowered and the manufacturing yield is remarkably lowered because it is difficult to control the surface roughness (projections and holes) and the thickness. Moreover, when producing an extremely thin product (18 μm or less), there are disadvantages of surface defects due to impurities and an increase in production cost.
The state of the thermal expansion coefficient of the iron-nickel alloy foil manufactured through the rolling process is shown in fig. 1.
Therefore, as a method that can replace the rolling process, an iron-nickel alloy foil is produced by an electroforming (electroforming) method.
The electroforming method is a method in which an electrolytic solution is supplied through a liquid supply nozzle to a gap surrounded by a rotating cylindrical cathode drum provided in an electrolytic cell and a pair of arc-shaped anodes opposed to the cathode drum, and an electric current is applied to the gap, thereby electrodepositing an Fe — Ni alloy on the surface of the cathode drum, and winding the electrodeposited Fe — Ni alloy to form a metal foil. The Fe — Ni alloy metal foil produced by the electroforming method has the advantages of fine average crystal grain size and excellent mechanical properties, and can be produced at low production cost.
However, even when an iron-nickel alloy foil is produced by electroforming, the thermal expansion coefficient may vary greatly depending on the crystal structure of the alloy foil, and the performance of the OLED product may be low.
Therefore, in the case of manufacturing an iron-nickel alloy foil according to the electroforming method, it is required to manufacture an iron-nickel alloy foil for OLEDs having a crystal structure capable of reducing the thermal expansion coefficient.

Detailed Description
The present inventors have intensively studied a scheme for reducing the thermal expansion coefficient of an iron-nickel (Fe-Ni) alloy foil produced by electroforming (electro forming). As a result, it was confirmed that the thermal expansion coefficient of the iron-nickel alloy foil changes depending on the crystal structure of the iron-nickel alloy foil.
Accordingly, the present invention is technically significant in providing an iron-nickel alloy foil having a crystal structure capable of reducing the thermal expansion coefficient.
The present invention will be described in detail below.
The iron-nickel (Fe-Ni) alloy foil according to one aspect of the present invention is produced by an electroforming method, preferably, the nickel content is 36 to 45 wt%, and the balance includes iron (Fe) and inevitable impurities, and has a Face-centered cubic (FCC) structure.
The iron-nickel alloy foil has a structure not having a face centered cubic structure (FCC), but having both a face centered cubic structure (FCC) and a body centered cubic structure (BCC), or having a body centered cubic structure (BCC), and thus cannot effectively reduce a thermal expansion coefficient, and is not suitable for use as a material for OLEDs.
More specifically, in the present invention, it is preferable that the ratio of the sum of the Texture coefficients of the (111) plane and the (200) plane to the sum of the Texture coefficients (Texture coefficients) of the (111) plane, the (200) plane, and the (220) plane is 80 to 98%, the ratio of the Texture Coefficient of the (111) plane is 60 to 78%, the ratio of the Texture Coefficient of the (200) plane is 20 to 30%, and the ratio of the Texture Coefficient of the (220) plane is 20% or less (including 0%).
If the dimensional range of the texture coefficient is not satisfied, the difference in thermal expansion coefficient occurs more in the width direction of the iron-nickel alloy foil, and therefore, there is a problem that the substrate and the mask are different in size in the vapor deposition step.
The Texture Coefficient (TC) is determined by obtaining the diffraction intensity Peak (Peak) value of each crystal plane by X-ray diffraction (XRD) as shown in fig. 2, and then converting the Peak value to the standard Peak value in the range of the following equation 2. In the following numerical formula 2, I (hkl) represents the measured diffraction intensity for the (hkl) plane, I
0(hkl) represents the standard diffraction intensity of ASTM (American society of Testing Materials ) standard powder diffraction data.
[ mathematical formula 2]
TC(hkl)≥{I(hkl)/I
0(hkl)}/[1/n∑{I(hkl)/I
0(hkl)}]
The iron-nickel alloy foil of the present application having the texture coefficient as described above preferably has a nickel content of 36 to 45 wt%.
When the nickel content is low, there is a problem that the thermal expansion coefficient rapidly increases, and therefore, the nickel content is preferably 36 wt% or more. However, if the content is too high and exceeds 45 wt%, the alloy foil has a thermal expansion coefficient much higher than that of glass or the like, and thus cannot be suitably used as a material for OLEDs.
Therefore, in the present invention, the nickel content of the iron-nickel alloy foil is preferably limited to 36 to 45% by weight.
The balance of the composition other than the nickel content is Fe. However, in a general manufacturing process, unintended impurities are inevitably mixed from raw materials or the surrounding environment, and thus cannot be excluded. These impurities are known to those skilled in the usual manufacturing processes and are not specifically mentioned in their entirety in this specification.
The iron-nickel alloy foil of the present application having the aforementioned texture and controlled nickel content can achieve a targeted low thermal expansion coefficient because the thermal expansion coefficient satisfies 3.0 to 5.0 ppm/K.
The iron-nickel alloy foil of the present invention has a surface roughness (Rz) of 2 μm or less, satisfies the requirements (JIS standard) required as a material for OLEDs, and has a characteristic that the weight variation in the width and length directions is 3% or less.
When the surface roughness (Rz) exceeds 2 μm, there is a possibility that a difference in etching depth may occur during the etching process due to surface unevenness.
Further, if the weight variation in the width and length directions of the alloy foil exceeds 3%, the physical properties vary on the surface, the curl increases, and the thermal expansion coefficient becomes uneven.
The weight deviation was calculated by cutting the iron-nickel alloy foil into an area of 5.8cm × 5cm to produce test pieces, measuring the weight of the test pieces, converting the weight into an iron-nickel alloy weight value per unit area, repeatedly cutting the test pieces along the width direction of the iron-nickel alloy foil, measuring the iron-nickel alloy foil weight value of each test piece, and calculating the standard deviation.
As described above, by forming the structure of the iron-nickel alloy foil into a face-centered cubic structure and controlling the interfacial ratio at that time, the strength and ductility can be secured to 1.0 to 1.5GPa and 1 to 5%, respectively.
The iron-nickel alloy foil of the present application having the above physical properties preferably has a thickness of 4 to 50 μm.
On the other hand, the iron-nickel alloy foil of the present invention can be manufactured according to an electroforming method, specifically, by providing a cathode and an anode in an electrolytic bath containing an electrolytic solution containing an iron compound and a nickel compound, and applying an electric potential by a current device, thereby electrodepositing an Fe — Ni alloy on the surface of the cathode.
In the present invention, the method for producing the iron-nickel alloy foil by the electroforming method is not particularly limited, and as a preferable example, an electrolytic solution containing iron at a concentration of 5 to 20g/L, nickel at a concentration of 20 to 50g/L, chlorine at a concentration of 20g/L or less (except 0), boron at a concentration of 5g/L or less (except 0), and o-sulfonylbenzoylimide at a concentration of 100ppm or less (except 0) is preferably used.
The boron and the o-sulfonylbenzoylimide in the electrolyte component are components added for obtaining a smooth and glossy alloy foil, and particularly the o-sulfonylbenzoylimide is a gloss agent for imparting gloss to the surface of the alloy foil to obtain a fine thin film layer, and is also a stress relaxation agent capable of relaxing stress.
Among them, ascorbic acid may be added in a small amount for the purpose of preventing oxidation of the electrolyte.
The remaining solvent of the electrolyte is preferably pure water, and more preferably, ultrapure water may be used.
The iron with a concentration of 5 to 20g/L may be dissolved in the form of a salt such as ferric sulfate, ferric chloride, ferric sulfamate, or electrolytic iron or iron powder may be dissolved in hydrochloric acid or sulfuric acid and supplied. The nickel having a concentration of 20 to 50g/L may be used in the form of a salt such as nickel chloride, nickel sulfate, or nickel sulfamate, or may be supplied by dissolving a nickel-iron alloy in an acid.
The Fe — Ni alloy foil produced by the electroforming method differs not only in the concentration of Fe and Ni in the electrolyte but also in the type and content of components separately added, process conditions, and the like. For example, it is important to control the concentration of iron in the electrolyte because the Fe content of the alloy increases if the concentration increases, and the Fe content increases if the current density decreases.
In particular, in the present invention, the concentrations of iron and nickel in the electrolyte and the process conditions at the time of electroforming are important means for obtaining a desired texture coefficient in the production of an iron-nickel alloy foil, and particularly, the relationship between iron ions and nickel ions in the electrolyte is preferably expressed by the following [ equation 1]]F _ Ni of
2+The value satisfies 72 to 78.
[ mathematical formula 1]
f_Ni
2+＝{[Ni
2+]/([Ni
2+]+[Fe
2+])}×100
(wherein, Ni
2+And Fe
2+Refers to the concentration of nickel ions and the concentration of iron ions in the electrolyte. )
In the case of iron-nickel alloy foil production by the electroforming method, a complicated state is exhibited due to abnormal codeposition (anomallous codeposition) of an alloy in which iron as a base metal precipitates earlier than nickel as a noble metal, and even if the ratio of ions dissolved in an actual solution is considered in order to obtain a desired composition, the Ni ion concentration should be relatively more than the Fe ion concentration in view of the electrodeposited electrodeposit combination.
Thus, in said [ mathematical formula 1]]F _ Ni of
2+When the value satisfies 72 to 78, an iron-nickel alloy foil having both a Face Centered Cubic (FCC) structure and a desired nickel content can be obtained.
If f _ Ni
2+If the value is less than 72 or exceeds 78, an iron-nickel alloy foil having a mixed crystal structure of FCC + BCC is formed, and the target level of thermal expansion coefficient cannot be secured.
When the electrolyte controlled as described above is used to obtain the iron-nickel alloy foil of the present invention, the pH is preferably 1.5 to 2.5, the temperature is preferably 45 to 70 ℃, and the pH is preferably 10 to 40A/dm
2Current density of 20 to 45m
3Flow rate conditions of/hr were performed.
In this case, if the pH is too low, the surface of the iron-nickel alloy foil is dented (pit) to make continuous operation impossible, and the nickel composition is lowered, so that it is difficult to produce an iron-nickel alloy foil having a desired composition. However, if the pH is too high, there is a problem that continuous operation cannot be performed due to electrolyte sludge, and there is a problem that the nickel composition rises excessively, and an iron-nickel alloy foil having a desired composition cannot be produced.
In view of this, it is preferable that the pH satisfies 1.5 to 2.5.
If the current density is too low or too high, a mixed FCC + BCC crystal structure is formed, and the nickel composition of the alloy foil cannot meet the target level.
Therefore, the current density is preferably 10 to 40A/dm
2The range is set so as to form an FCC crystalline structure.
In addition, even when the temperature is too high or the flow rate is too low, a mixed crystal structure of FCC + BCC is formed.
Also, there is a problem in that if the temperature is too high or the flow rate is too low, the nickel composition is decreased, and conversely, if the temperature is too low or the flow rate is too large, the nickel composition is increased.
Therefore, the temperature is preferably controlled to be 45-70 ℃, and the flow is preferably controlled to be 20-45 m
3And/hr, and within this range is disposed in a manner to form an FCC crystalline structure.
The present invention will be described more specifically with reference to examples. It should be noted, however, that the following embodiments are only illustrative and specific for the present invention, and are not intended to limit the scope of the present invention. This is because the scope of the present invention is determined by the matters recited in the claims and reasonably analogized therefrom.
