36Functional Polymer ScienceMusubu IchikawaTapping organic EL to bring us future products such as televisions that can be rolled up and carried and ceilings with built-in lightingDepartment of Chemistry and MaterialsI am carrying out research into organic EL (organic LED), an area that is the focus of increasing expectations concerning potential applications in next-generation displays and lighting. Multinational corporations from outside Japan are also showing interest, and my lab is cooperating with them. If successful, it will become possible to make entire ceilings and walls into lighting and to make televisions and computer monitors that can be rolled up and carried around. Currently, our major challenge is to reduce power consumption.Professor Ichikawa took his current position in 2013 after working at the Ube Industries Polymer Research Center and as an assistant professor and associate professor in the Faculty of Textile Science and Technology at Shinshu University. His areas of research are functional materials and devices and physical chemistry, including organic semiconductor devices and organic photoelectric materials.In addition to research into organic EL, research is also being actively conducted into organic semiconductors and organic solar cells, and these products are expected to contribute to the realization of an abundant and sustainable society.Outlook for researchGraduates are employed by material, chemical, and electrical equipment manufacturers, while some students are employed by major printing companies that are involved in organic EL development.Outlook for students after graduationAn organic semiconductor material developed in the research lab is melted and applied to a circuit board to create a transistor. We are carrying out research to create example uses that leverage its properties.An organic EL. Unlike LEDs, the principal characteristic of an organic EL, a conductive polymer, is that it emits light from a form like a thin membrane.ProfessorFunctional Polymer ScienceDeveloping environmentally friendly organic materials that can be easily broken down and recycled after useDepartment of Chemistry and MaterialsCleavable materials, which can be converted into non-toxic substances under mild conditions after use, have been receiving a great deal of attention. If materials can be broken down and recycled when needed, they are not only environmentally friendly, but also functional. I am pursuing research to add chemical degradability to commonly used organic materials such as surfactants and plastics.Professor Itoh took his current position in 2009 after serving in the Faculty of Textile Science and Technology at Shinshu University as an assistant professor and associate professor. His areas of research include synthetic polymer chemistry, photochemistry, and organic material chemistry.My lab is developing organic materials that can be quickly broken down and recycled after use through simple exposure to light or addition of weak acids or alkalis. The addition of such chemical degradability to commercial products will transform them into high-performance, eco-friendly materials that are available for use in numerous industrial elds and in everyday life.Outlook for researchMany graduates are employed by chemical companies in the manufacture of paints, adhesives, lms, plastics, and other products.Outlook for students after graduationYoshihiro ItohProfessorImmediately after adding a small amount of a weak alkali to an aqueous surfactant (detergent) solution, bubbles disappear and solids (hydrolyzed product) precipitate.6 μm 60 μm Micrograph of a latex paint-coated ber surfaceMicrograph of a latex paint-coated paper surfacePhotograph of carbon-black latex ink-coated paperHydrolyzable surfactant-containing polymer particles (latex) are utilized as quick-drying water-based paints and pigment inks.
