Disclosed herein are a method for manufacturing a functional material for use in various industrial fields in which anisotropy or physical properties change according to height may be utilized, as well as a functional material manufactured thereby. The method includes the steps of: (1) mixing powders composed of the components of the functional material with a binder to prepare a mixed paste; (2) coating the mixed paste on a substrate, and then separating the coated material from the substrate, thus preparing a slice; (3) repeating step (2) to prepare a plurality of slices, and stacking the slices in a mold; and (4) pressing the stacked slices at a predetermined temperature and pressure. A multifunctional material, such as an anisotropic material having physical properties which change according to the direction of material, or a material having physical properties which change in a graduated manner according to height, may be manufactured in a simple and economical manner.

The present invention relates to a method for manufacturing a functional material, such as an anisotropic material whose physical properties differ according to direction, a material which has physical properties which change according to height, and a thermoelectric material which is used for thermoelectric cooling and thermoelectric power generation, and more particularly to a method of manufacturing a functional material in a simple and economical manner by preparing slices corresponding to the components of the functional material and pressing the slices.
As used herein, the term “functional material” refers to an anisotropic material having electrical, optical, thermal, chemical or mechanical properties which change in the horizontal, vertical or diagonal direction with respect to the surface, a material having physical properties which differ according to height, or a material having physical properties which change regularly, irregularly or continuously according to height in a graduated manner. That is, it refers to a material showing various functions because of such anisotropy or physical properties which change in a graduated manner.
Functional materials having such physical properties may be used as thermoelectric materials in kitchen utensils, electric home appliances or thermoelectric elements, and such anisotropy or physical properties changing in a graduated manner also have an application in various industrial fields.
The above and other objects, features and advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:

FIG. 2 illustrates an optical micrograph (a), Fe-SEM photograph (b) and EDS date (c) of a slice separated from a copper foil according to an embodiment of the present invention;
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic diagram showing a method for manufacturing a functional material according to the present invention. As shown therein, the present invention relates to a method for manufacturing a functional material, the method comprising mixing powders composed of the components of the functional material with a binder to prepare a mixed paste 10, coating the mixed paste 10 on a substrate 20, and separating the coated material from the substrate 20 to prepare a thick film slice 30 consisting of the component of the functional material.
In addition, the method comprises stacking the slices 30 in a predetermined mold 40 and pressing the stacked slices 30 with a press 50 at a predetermined temperature and pressure. According to the inventive method, a multifunctional material 100 which shows anisotropy and whose physical properties change according to height may be manufactured in a simple manner.
