Discovering the Knowledge Structure of Graphene Technology by Text Mining National R&D Projects and Newspapers

Abstract

Graphene, called the “dream material” is drawing attention as a groundbreaking new material that will lead the era of the 4th Industrial Revolution. Graphene has high strength, excellent electrical and thermal conductivity, excellent optical permeability, and excellent gas barrier properties. In this paper, as the South Korean government recently announced Green New Deal and Digital New Deal policy, we analyze graphene technology, which is also attracting attention for its application to Corona 19 biosensor, to understand its national R&D trend and knowledge structure, and to explore the possibility of its application. Firstly, 4,054 cases of national R&D project information for the last 10 years are collected from the National Science & Technology Information Service(NTIS) to analyze the trend of graphene-related R&D. Besides, projects classified as green technology are analyzed concerning the government s Green New Deal policy. Secondly, text mining analysis is conducted by collecting 500 recent graphene-related articles from e-newspapers. According to the analysis, the field with the largest number of projects was found to be high-efficiency secondary battery technology, and the proportion of total research funds was also the highest. It is expected that South Korea will lead the development of graphene technology in the future to become a world leader in diverse industries including electric vehicles, cellular phone batteries, next-generation semiconductors, 5G, and biosensors. ■ keyword :∣Graphene Technology∣Text Mining∣News∣R&D Project Information∣Knowledge Structure∣ * 본 연구는 2020년도 한국과학기술정보연구원(KISTI) 주요사업 과제로 수행한 것입니다(NTIS 과제고유번호 1711120559). 접수일자 : 2020년 09월 23일 수정일자 : 2020년 10월 12일 심사완료일 : 2020년 10월 12일 교신저자 : 이병희, e-mail : [email protected] 한국콘텐츠학회논문지 21 Vol. 21 No. 2 86
