Abstract: Disclosed is an ultrafine fiber including lignin, a carrier polymer and a carbon material. The ultrafine fiber, which includes lignin, can exhibit the properties of lignin such as antibacterial property, biodegradability, etc. Accordingly, it can be used widely in medical materials such as nanofiber, nanofiber web, nanofiber sheet, etc. for wound healing of the skin's dermal layer. Also, the ultrafine fiber can be used in sheath of electric cables because it contains a carbon material and has superior conductivity. In addition, because the ultrafine fiber can hold a large quantity of water, it can be used in various fields including sanitary pads for women, diapers for babies and adults, etc.

Abstract: A radar-absorbing fiber-reinforced structure includes a fiber composite discharging part. The fiber composite discharging part includes a first electrode part and a second electrode part, which are spaced apart from each other by a dielectric layer and receive different voltages. The fiber composite discharging part is configured to discharge plasma in response to a voltage difference thereby changing a reflected wave or transmitted wave of a radar incident on the radar-absorbing fiber-reinforced structure to reduce reflectivity of the radar. At least one of the first electrode part and the second electrode part include a conductive fiber having a tensile strength equal to or more than 0.5 GPa.

Abstract: Disclosed are lignin microcapsules including lignin as a shell material and at least one of oil and a carbonaceous material as a core material. The lignin microcapsules may be formed by carried out polymerization in an oil-in-water emulsion including lignin, oil and water and further including a carbonaceous material. Since lignin has a phenol structure, the microcapsules including lignin may be formed to have antibacterial property. Thus, the lignin microcapsules may be used widely in various fields, such as additives for composite materials.
Abstract translation: 公开了包括作为壳材料的木质素和作为核心材料的油和碳质材料中的至少一种的木质素微胶囊。 木质素微胶囊可以通过在包含木质素，油和水的水包油乳液中进行聚合并进一步包含含碳材料来形成。 由于木质素具有酚结构，因此可以形成包含木质素的微胶囊以具有抗菌性。 因此，木质素微胶囊可以广泛用于各种领域，例如复合材料的添加剂。
