Here, we developed an ultra-high-resolution printing technique based on “ surface selective deposition ” that can deposit functional inks with 1-μm resolution on flexible substrates. We used this technique to selectively deposit a metal nanoparticle ink and an organic semiconducting material, thereby allowing the large-scale fabrication of high-resolution electronic circuits including organic thin-film transistors with channels as short as 1 μm under ambient atmosphere. We also developed π -junction gold nanoparticles as the electrode material which permitted room-temperature deposition of a conductive metal layer. The room-temperature process enables printing of electronic circuits without application of heat, thus thermal damage to the substrate can be totally avoided. These results indicate that this bottom-up fabrication method based on fluidic self-assembly is promising for the fabrication of large-area, high-resolution, low-cost electronics.","PeriodicalId":13075,"journal":{"name":"Hyomen Kagaku","volume":"82 1","pages":"222-227"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90265026","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}

In this paper, I summarize and review the recent progress of gas barrier enhancement of polyethylene terephthalate (PET) bottles for beverage from the view point of the application of DLC coating. A unique technique of plasma CVD method has been developed to deposit DLC layer on the inside surface of PET bottles. The DLC-coated PET bottle exhibits extremely high gas barrier properties against oxygen, carbon dioxide and flavors compared to conventional bottles. For the practical use of PET bottles as a commodity, machines have been introduced for soft drink, wine, Japanese sake, edible oil, seasonings and others.","PeriodicalId":13075,"journal":{"name":"Hyomen Kagaku","volume":"52 1","pages":"240-243"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75918256","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}

A Co silicide films is formed through reaction between a Co thin film and the underlying Si wafer. During this process, however, a TiN cap film must be formed to prevent the Co thin film from forming Co nanoparticles and must be etched after the formation of the silicide film, which makes the formation process complicated. In this study, we optimized the thickness of the Co film and formed a silicide film without using a TiN cap film to simplify the formation process. As a result, the formation of the Co nanoparticles was greatly suppressed during the formation of a silicide film. Using the Co silicide film obtained after the formation process at 650°C for 10 min as the support of catalytic Co nanoparticles, vertically aligned CNTs film with a thickness of 5.3 μm were obtained by hot-filament chemical vapor deposition (CVD) with ethanol steam at 450°C for 30 min.
