Description
The present invention relates to a method for producing pitch-based carbon fibers with improved thermal conductivity by electroless plating, and more particularly, to a method for producing pitch-based carbon fibers having a high thermal conductivity by efficiently modifying the surface of pitch- To a method of producing fibers.
BACKGROUND ART [0002] In recent years, electronic devices used in automobiles, electric and electronic fields have been sought to be lightweight, thin, miniaturized, and multifunctional. The emission heat generated by the high integration of such electronic devices not only degrades the function of the device but also causes malfunction of peripheral devices and deterioration of the substrate.
As a result, materials with a certain level of thermal conductivity have been actively developed. Carbon-based materials have high thermal conductivity, excellent mechanical properties, and light weight, so they are attracting attention as new materials that are expected to be applied in fields requiring high- .
A typical carbon material used as a filler for thermally conductive composites is carbon fibers.
A lot of studies have been conducted to develop functional carbon fibers. Korean Patent Registration No. 10-1096531 by the applicant of the present application discloses a method for producing carbon fibers having high electrical conductivity by using an electrolytic plating solution.
In addition, Korean Patent Registration No. 10-1197723 by the applicant of the present application discloses a method for producing carbon fibers having improved electrical conductivity by plating with a nickel-phosphorus alloy on the surface of carbon fibers produced by electrospinning. However, All of the techniques provide carbon fibers with improved electrical conductivity, and the use of composite materials having heat dissipation properties is inferior.
Carbon fibers are classified into rayon based carbon fiber made from rayon fiber, PAN based carbon fiber made from polyacrylonitrile fiber, pitch carbon fiber made from coal tar and petroleum residue according to the precursor Currently, PAN-based carbon fibers account for nearly 90% of the market.
PAN-based carbon fiber is a composite material used as a material for aircraft bodies, wings, structural materials, golf clubs, racquets, and fishing rods. However, due to the low productivity due to the slow chemical reaction and high energy consumption, And defects caused by the defect.
The pitch-based carbon fiber is classified into an anisotropic pitch system and an isotropic pitch system depending on the crystal state of the emitted pitch. The pitch structure itself is similar to the graphite, which is a carbon fiber structure, It consumes less energy. In addition, the pitch-based carbon fiber has a lower yield than the PAN-based carbon fiber because the ratio of impurities N 2 , H 2, and other carbon materials is low. Furthermore, it has a higher electric and thermal conductivity than PAN-based carbon fiber, and can expand its market to demand products that require functionality. In particular, anisotropic pitch carbon fibers are known to be superior to PAN-based carbon fibers in terms of cost competitiveness due to their high crystallinity, easy graphitization, and low cost of raw materials using residual oil. In spite of these high-performance and economical properties, the use of pitch-based carbon fibers has not been widely utilized.
An object of the present invention is to provide a method for manufacturing pitch-based carbon fibers having improved thermal conductivity by performing electroless metal plating on pitch-based carbon fibers through a simple process for popularization of pitch-based carbon fibers through multiple utilization .
In order to accomplish the above object, the present invention provides a method of manufacturing a semiconductor device, comprising: (1) mixing a metal compound with an acid solution; (2) removing foreign matters on the surface of the pitch-based carbon fiber by using the mixed solution prepared in the step (1), and introducing metal nuclei contained in the metal compound to modify the surface; (3) And carbonizing the pitch-based carbon fiber surface-modified by the step (2) to obtain a metal-coated pitch-based carbon fiber.
In the step (1), the acid solution is mixed with one or more selected from the group consisting of HCl, HNO 3, H 2 SO 4, and H 3 PO 4 and has a concentration of 1 to 10 M.
In the step (1), SnCl 2 .2H 2 O and PdCl 2 are used as the metal compound, and the concentration is in the range of 0.001 to 0.1M.
The plating solution for metal plating in the step (3) is characterized by comprising a nickel salt, a phosphoric acid-based reducing agent, and a complexing agent.
Wherein the pH of the plating solution for metal plating in the step (3) ranges from 3 to 10, and the plating time ranges from 10 to 180 seconds.
According to the present invention, there is provided a method for manufacturing pitch-based carbon fibers having improved thermal conductivity by performing electroless metal plating on pitch-based carbon fibers, thereby providing economical efficiency through mechanical methods and improving the thermal conductivity of pitch- And also has an effect of being useful in manufacturing a material having a heat radiation characteristic by compositing with a material having a relatively low thermal conductivity inherently due to an improvement in thermal conductivity.
1 is an X-ray diffraction (XRD) graph of electroless nickel plated petroleum pitch-based carbon fibers according to the present invention.
Hereinafter, the present invention will be described in detail.
(1) mixing a metal compound with an acid solution; (2) removing foreign matters on the surface of the pitch-based carbon fiber by using the mixed solution prepared in the step (1), and introducing metal nuclei contained in the metal compound to modify the surface; (3) And carbonizing the pitch-based carbon fiber surface-modified by the step (2) to obtain a metal-coated pitch-based carbon fiber.
In the step (1), the acid solution may be prepared by mixing one or more selected from the group consisting of HCl, HNO 3, H 2 SO 4, and H 3 PO 4 , and the concentration is 1 to 10 M, Treatment with 6M shows the best effect. The reason for treating the acid solution is to remove impurities such as an oxide film and hydroxides on the surface of the pitch-based carbon fiber. When the concentration is less than 1M, the surface modification is difficult to be effectively performed. When the concentration exceeds 10M, It is preferable that the concentration of the acid solution is 1 to 10M.
In the step (1), SnCl 2 .2H 2 O and PdCl 2 are used as the metal compound, and the concentration is in the range of 0.001 to 0.1M. 0.05 to 0.1 M in the case of SnCl 2 .2H 2 O, and 0.01 to 0.05 M in the case of PdCl 2 show optimum effects. If the concentration of SnCl 2 .2H 2 O and PdCl 2 is less than 0.001M, the introduction of metal nuclei is difficult due to the concentration too low. If the concentration exceeds 0.1M, the metal particles will block the pores on the surface of the carbon fiber, . Therefore, the concentration of SnCl 2 .2H 2 O and PdCl 2 is preferably in the range of 0.001 to 0.1M. At this stage, Sn / Pd nuclei are formed, and the Sn / Pd nuclei formed on the carbon fiber surface can promote the deposition of metallic nickel.
The plating solution for metal plating in the step (3) is characterized by comprising a nickel salt, a phosphoric acid-based reducing agent, and a complexing agent. The nickel salt is preferably NiCl 2 .6H 2 O, the phosphoric acid reducing agent is preferably NaH 2 PO 2 .H 2 O, and the complexing agent is preferably NaC 6 H 5 O 7 .2H 2 O. The nickel ion of the nickel salt forms the nickel film on the surface of the pitch-based carbon fiber by the reducing agent contained in the plating solution. The complexing agent improves the stability by delaying the plating rate and serves as a buffer to prevent rapid pH change of the solution due to hydrogen ion generated during plating.
In the step (3), the pH of the plating solution for metal plating is preferably in the range of 3 to 10, preferably 4 to 8. If the pH is less than 3, the quality of the plating layer may be lowered and the plating efficiency may be lowered. If the pH exceeds 10, the plating solution may cause self-decomposition. Therefore, the pH of the plating solution is preferably in the range of 3 to 10.
In the step (3), the plating time is in the range of 10 to 180 seconds. If the plating time is less than 10 seconds, the reaction time is too short, which is undesirable because the amount of the alloy produced on the surface of the pitch-based carbon fiber is small. If it exceeds 180 seconds, the metal layer on the surface of the pitch- Which is undesirable because it becomes thick enough to lose its inherent properties. Therefore, the plating time is preferably in the range of 10 to 180 seconds.
Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood by those skilled in the art that these examples are for illustrative purposes only and that the scope of the present invention is not construed as being limited by these examples.
