CNT와 Graphene을 중심으로 나노 재료의 직물에서의 활용에 대한 연구

Abstract

One of the main reason of the disastrous fire is polymer which is used in livelihood. Because polymers are organic materials combined carbon, hydrogen and oxygen, polymers are vulnerable to heat. To decrease the disastrous polymers are necessary flame retardant which are additives not to burn by improving the inflammability of a polymer. The research method is as follows.BR Firstly, introduction of the fire retardant which are used in textile is variously used as not only household clothing but also all sorts of livelihood items. Development of fire retardant facilitates not only reinforcing fire retarding but also producing fabric with various functions such as sterilization, deodorization, and water repellent, so makes the use in the present restricted fields spread to new uses. Production of this multifunctional fabric facilitates combining existing fabric field with the field of engineering related to disaster prevention.BR Secondly, presentation of Kinds of fire retardants which are divided into addition fire retardant and responsive fire retardant. Addition fire retardant is a method mixing it simply by putting it as additive during compounding process, and responsive fire retardant gives fire retarding by producing a fire retarding polymer by introducing a monomer giving fire retarding to main chain of a polymer, or by combining fire retarding substance chemically in the end or side chain of a polymer by introducing reactive groups into a polymer.BR Thirdly, the introduction of nanocomposite fire retardants such as CNT or graphene fire retardants emerging from a limit of existing fire retardants reduces true character of fabric. Carbon nanotube CNT) is an allotrope of carbon with cylindroid nanostructure. Graphene is also one of carbon allotropes and has a structure that carbon atoms gather become 2D plane.BR Finally, CNT and graphene are overviewed as the promising materials for the flame retardant. The various results of CNT and graphene as nanofiller to retard the fire are mentioned. By the understanding of the retardation properties of those material, textile industry in the areas of clothing and household items will be more easily convergence with the nanotechnology.
