Abstract:
A heat insulation sheet includes: a heat insulation layer formed as a nanofiber web form having a plurality of pores by electrospinning a polymeric material; and an adhesion layer laminated on one or both sides of the heat insulation layer and formed as a nanofiber web form by electrospinning an adhesion material, to thereby be made thin and have a plurality of fine pores, and to thus improve heat insulation performance.
Abstract:
Provided is matte film including: a film layer that is formed in a nano-web shape by electrospinning a polymer material; an ink layer that is coated on one surface of the film layer; and an adhesive layer that is laminated on the other surface of the film layer through electrospinning. Since the film layer is formed in a nano-web shape so that fiber strands are accumulated, the matte film can be thinly produced and have a non-glossy function of performing scattered reflection of light and a fingerprint-preventive function of making fingerprints imprinted. Further, the surface strength of the matte film can be reinforced.

Abstract:
Provided is an adhesive tape including: a substrate; and an adhesive layer laminated on one surface or both surfaces of the substrate, wherein one or both of the substrate and the adhesive layer are produced in a nano-web form in which fiber strands are captured by a spinning method. Thus, the adhesive tape can be made thin, and an adhesive strength can be improved. In addition, the adhesive tape can be precisely attached on a corrugated surface. When the adhesive tape attached between components is separated from the components, the adhesive layers can be prevented from remaining on the surfaces of the components.

Abstract:
Provided is a conductive adhesive tape comprising: a substrate that is formed in a nano-web form having a number of pores by spinning a polymer material by a spinning method; and a conductive adhesive layer that is formed in a non-porous form by directly spinning a conductive adhesive material by a spinning method on one or both surfaces of the substrate, or that is laminated on one or both surfaces of the substrate. Accordingly, thickness of the adhesive tape can be made thin, adhesive strength of the adhesive tape can be enhanced, and the adhesive tape can be precisely attached on even a curved surface. Further, when removing the adhesive tape from components, the adhesive layer can be prevented from remaining on the surface of the components.
