Description
본 발명은 전자섬유 및 이의 제조방법에 관한 것으로서, 더욱 상세하게 생체 접착 물질을 포함하는 접착층을 포함하고 상기 접착층의 외주면에 그래핀층 또는 금속나노입자층을 형성한 전자섬유 및 이의 제조방법에 관한 것이다.The present invention relates to an electronic fiber and a method for manufacturing the same, and more particularly, to an electronic fiber including an adhesive layer containing a bioadhesive material and having a graphene layer or a metal nanoparticle layer formed on an outer circumferential surface of the adhesive layer, and a method of manufacturing the same.
전자 섬유는 휴대용 유연 디스플레이 기능, 생체 신호 진단 기능, 위험 가스 센싱 기능, 에너지 저장 기능 등을 비롯해 입는 컴퓨터 (Wearable computer)의 구현까지, 다양한 분야에 적용이 가능하여 아주 큰 관심을 받고 있다. 이런 기능을 구현하기 위해서 전자섬유는 전도성을 포함한 내구성, 휘어짐, 착용 및 세탁 가능, 소재의 경량성이 우수해야 하기 때문에 전 세계적으로 그래핀 (Graphene) 섬유 개발이 활발히 이루어지고 있다. 하지만 현재까지 발표된 전자섬유는 기존 섬유에 적용하기 어려운 제약이 있다.Electronic fibers have attracted much attention because they can be applied to various fields ranging from portable flexible display function, bio signal diagnosis function, hazardous gas sensing function, energy storage function to the implementation of a wearable computer. Graphene fibers have been actively developed around the world because of their durability, warpage, ability to be worn and washed, and light weight of materials to achieve such functions. However, the electronic fibers announced so far have limitations that are difficult to apply to conventional fibers.
본 발명은 생체 접착물질을 이용해 현재 사용되고 있는 섬유 즉, 면, 나일론, 폴리에스터 등을 그래핀 산화물로 감싸게 한 후, 화학적 방법으로 그래핀 산화물을 환원하는 과정을 거치게 된다.In the present invention, graphene oxide is wrapped in fibers, cotton, nylon, polyester, etc., which are currently used by using a bioadhesive material, and then the graphene oxide is reduced by a chemical method.
결과적으로 기존 섬유 혹은 신섬유인 나노 섬유 등을 손쉽게 전자섬유를 만들 수 있을 뿐 아니라, 현 의류 산업에 바로 적용이 가능하다는 장점이 있다. 본 발명의 전자섬유 제조기술은 미래 전자 및 섬유 산업 관련시장에서의 경쟁력을 강화하고 유비쿼터스 환경에 적합한 지능형 의류 개발에 표준화를 선도하는 데에도 크게 기여할 수 있을 것으로 기대된다.As a result, it is possible to easily make electronic fibers such as existing fibers or nanofibers such as new fibers, and it is possible to apply them directly to the current clothing industry. The electronic fiber manufacturing technology of the present invention is expected to contribute to strengthening competitiveness in the future electronic and textile industry related market and leading standardization in the development of intelligent clothes suitable for ubiquitous environment.
한편, 관련 선행기술로는 한국등록특허 제10-1233818호(그래핀이 처리된 섬유의 제조방법) 등이 있다.On the other hand, Korean Prior Registration No. 10-1233818 (a method of producing graphene-treated fiber) is known as a related art.
본 발명자는 전자섬유를 제조함에서 있어서 기존의 방법들은 기존 섬유에적용하기 어려울 뿐만 아니라, 전기전도성을 부여하기 위해 그래핀층 또는 금속나노입자층을 형성함에 있어서 기존에 사용되어왔던 접착물질(인산염 등)은 섬유와의 접착성이 약하여 최종적으로 만들어진 전자섬유의 전기전도도가 현저하게 낮은 문제점이 있음을 개선하기 위해 예의 노력한 결과 생체 접착 물질(보바인 세럼 알부민 등)로 이루어진 접착층을 형성시키고 상기 접착층의 외주면에 그래핀층 또는 금속나노입자층을 형성할 경우 기존섬유에 손쉽게 적용하여 전도성, 유연성, 내화학성이 우수한 전자섬유를 제조할 수 있을 뿐만 아니라 상기 인삼염을 접착물질로 사용하는 경우와 비교하여 1,000배 내지 10,000배 이상의 높은 전기전도도가 확보되는 것을 실험적으로 확인함으로써 본 발명을 완성하게 되었다.The present inventors have found that conventional methods for producing electronic fibers are difficult to apply to existing fibers, and that they are difficult to apply to existing fibers in the formation of graphene or metal nanoparticle layers to impart electrical conductivity, The adhesive layer of the biofouling material (such as bovine serum albumin) is formed as a result of efforts to improve the problem that the electrical conductivity of the finally formed electronic fiber is remarkably low because of low adhesiveness to the fibers, It is possible to produce electronic fibers having excellent conductivity, flexibility and chemical resistance by easily applying them to conventional fibers when forming a graphene layer or a metal nanoparticle layer, It is experimentally confirmed that a high electric conductivity of 10,000 times or more is secured Thereby completing the present invention.
결국, 본 발명의 목적은 생체 접착 물질로 이루어진 접착층을 포함하고 상기 접착층의 외주면에 형성되는 그래핀층 또는 금속나노입자층을 포함하는 전자섬유를 제공하는데 있다.It is an object of the present invention to provide an electronic fiber including an adhesive layer made of a bioadhesive material and including a graphene layer or a metal nanoparticle layer formed on the outer peripheral surface of the adhesive layer.
