    Print production of high performance thin film transistors (TFT) is most important challenge that needs to be overcome in order to realize “printed electronics” technology. Recently, we developed a novel double-shot inkjet printing technique that combines the technique of “antisolvent crystallization” with the microfluidic inkjet printing processes. By using this technique we demonstrated the controlled formation of highly uniform single crystal films, print production of single crystal film arrays and fabrication of high performance organic TFTs.

  • Preparation of Organic-Inorganic Hybrid Materials by Photo-crosslinking Reaction

    Organic-inorganic hybrids are attractive materials with characteristics of both inorganic substances and organic polymers. The various functions derived from their chemical structures offer great potential for practical usages. As an effective method for bonding dissimilar components, the simultaneous photo-crosslinking by organic reactions, such as radical polymerization, cationic polymerization, thiolene reaction and sol-gel reaction are useful. In addition, photo cross-linking organic-inorganic hybrids can also be synthesized from a polysilsesquioxane having a photoreactive group. These organic-inorganic hybrid thin films are very transparent and these hybrids are interesting as optical materials with a controlled refractive index.

  • Miscibility of Polymers in Adhesives
    Toshiaki OUGIZAWA
    2015 Volume 88 Issue 2 Pages 44-50
    Published: February 20, 2015

    In most adhesives that have been put to practical use, the polymers are principal ingredients. Therefore, when the polymers are mixed, the knowledge concerning the miscibility between polymers is very important to improve the performance. In addition, the miscibility is important as it significantly affects the interfacial phenomena and can help to provide an understanding of the adhesive interface. In this article, the miscibility between polymers is briefly explained and then some of the phenomena associated with it are introduced.

  • The Introduction and Recent Topics of Zinc-Rich Paint
    Kentaro MIZUSHIMA
    2015 Volume 88 Issue 2 Pages 51-55

    Among anti-corrosive primer coatings for steel structures such as ships and bridges, zinc-rich paints are the most important type due to their sacrificial anti-corrosive function. The present article describes the anti-corrosive reaction mechanisms of zinc-rich paint, the features of various zinc-rich paints (organic and inorganic types) and practical problems that occur at the painting site. Furthermore, the development of “Weak solvent-based zinc-rich paint” and “Thin layer type shop primer” are introduced as recent topics in this field.
