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: 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: Provided herein are a sulfur copolymer derived from an elemental sulfur and a thiol monomer and a method for preparing the same. The sulfur copolymer is synthesized by a simple method, and can be widely used in cameras and lenses, or defense materials-related industries, by replacing expensive inorganic materials used in existing infrared lenses. In addition, by adjusting the content of one or more sulfur monomers or two or more sulfur monomers, not only mid-wave infrared transmission but also long-wave infrared transmittance can be maintained at a high level.
