Abstract: Provided is an aerogel-containing heat insulation composite obtained by providing a volatile material to the pores of the aerogel, blending the aerogel with a polymer resin, particularly a flexible polymer resin, to form a composite, and removing the volatile material. Thus, it is possible to prevent a decline of the porosity of the aerogel caused by infiltration and impregnation of the pores of the aerogel with the resin. As a result, the aerogel-containing heat insulation composite, particularly containing a high content of aerogel, may retain the heat insulation property of the aerogel as well as the flexibility of the plastic material.

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 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.
