Abstract: Electromagnetic wave shielding material including a conductive fiber web with multiple pores and a heat dissipation unit provided in at least some pores that is so excellent in flexibility, elasticity, and creasing/recovery that it can be changed in shape freely and brought in complete contact with a surface where the material is to be disposed even if the surface has a curved shape, uneven portions, or stepped portions, thus exhibiting excellent electromagnetic wave shielding performance and prevent deterioration thereof despite various shape changes. Since heat dissipation performance is excellent, heat generated in an electromagnetic wave source can be rapidly conducted and released. Even if parts are provided in a narrow area at high density, the material can be brought in close contact with mounted parts by overcoming a tight space between the parts and a stepped portion. The invention is employed for light, thin, short, and small or flexible devices.

Abstract: Provided is a fiber web for a gas sensor. In one exemplary embodiment of the present invention, there is provided a fiber web for a gas sensor including nanofibers including a fiber-forming material and a sensing material for reacting with a target substance in a test gas. According to the exemplary embodiment, the fiber web for a gas sensor is capable of identifying the presence or absence of a target substance in a test gas and quantitatively determining the concentration of a target substance, and exhibits improved sensitivity due to having an increased area of contact and reaction with a target substance contained in a test gas. In addition, the fiber web for a gas sensor facilitates the detection of a target substance in a test gas at a low cost and thus can be widely used for the detection of various volatile organic compounds (VOCs) in households, the diagnosis of asthma or esophagitis or the identification of a patient suffering from the same, and the detection of hazardous materials in other fields of industrial safety.

Abstract: A method for manufacturing a flexible printed circuit board includes preliminarily thermally deforming s substrate through heating, forming a circuit pattern with a conductive paste on the preliminarily thermally deformed substrate, and firing the circuit pattern. A flexible printed circuit board includes a substrate, and a circuit pattern formed by firing a conductive paste on a first surface of the substrate. The substrate is preliminarily thermally deformed and, thus, a shrinkage variation thereof before and after firing the conductive paste is zero. Dimensional stability when firing the circuit pattern printed with the conductive paste can be ensured, deterioration of adhesion between the circuit pattern and the substrate attributable to film deformation upon firing can be prevented, and stable adhesion of the circuit pattern can be maintained even after firing.

Abstract: Provided is yarn for a cell culture scaffold. The yarn for a cell culture scaffold according to an exemplary embodiment of the present invention includes slitting yarn produced by cutting a compressed nanofiber web to a predetermined width. Accordingly, by creating microenvironments suitable for migration, proliferation and differentiation of cells, cell viability may be enhanced and cells may be three-dimensionally proliferated. In addition, a scaffold according to the present invention has a mechanical strength sufficient for prevention of disruption of the scaffold which occurs during cell culture, such that cells may be stably proliferated. Further, the scaffold according to the present invention uses slitting yarn formed of the compressed nanofiber web, thereby having pores with various sizes, and therefore cell proliferation and cell viability may be enhanced by creation of an extracellular matrix-like environment.

Abstract: A coil component having a magnetic core, a bobbin accommodating the magnetic core, and at least one pair of coils wound around the outer part of the bobbin. The bobbin is implemented as a heat radiating member comprising: a polymer matrix; and graphite-nano metal composites which are provided in a plurality, are dispersed on the polymer matrix, and have nano-metal particles bonded to the surface of graphite. Accordingly, the heat generated from a coil component due to an applied current can most quickly and efficiently be conducted and radiated outside, and thus degrading of common-mode-noise rejection function is prevented and a differential signal can substantially be passed without attenuation. In addition, in spite of the heat generated from the coil component or external physical and chemical stimulation, heat radiating properties can last for a long time.
