Development of this material is still an active area of research, world-wide, because the expected high electric and heat conductivity and mechanical strength properties are difficult to obtain with other existing materials. However, low growth efficiency of single-walled CNTs has made the cost of production high compared to that of multi-walled CNTs. Consequently, commercialization of single-walled CNTs has taken longer to develop than multi-walled CNTs. To address this problem, a super-growth process was developed at the National Institute of Advanced Industrial Science and Technology (AIST) that uses an innovative chemical vapor deposition (CVD) method. The super-growth method opens the door to a range of industrial applications widely. This report describes the development of this process for industrial scale, mass production of high quality single-walled CNTs, with commercialization in mind, from the perspective of business-academia collaboration.","PeriodicalId":39206,"journal":{"name":"Synthesiology","volume":"93 1","pages":"167-179"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5571/SYNTHENG.9.3_167","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70697988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
