照明の開発－ Latest Trends and Challenges in OLED Lighting Technologies |
岩崎 利彦 Toshihiko IWASAKI |
| ＜要旨＞ We
report recent progress and future prospects of OLED lighting based on
KONICA MINOLTA’s development activities. We have been working on two
approaches, vacuum thermal evaporation and solution processing, to make
white OLED lighting using proprietary blue phosphorescent technology.
In 2011, the world's first all-phosphorescent OLED lighting panel was
brought into market, which has been the best candidate technology to
achieve the attractive performance as the lighting application, especially
considering efficacy. On the other hand, we demonstrated the feasibility of the solution-processed OLED technology by showing unique OLED lighting prototype fabricated by the roll-to-roll R&D line in 2010. Though solution-processed OLED has potential for high productivity and large-scale fabrication capability, it is widely believed that the device performances fabricated by the solution process are inferior to that of vacuum process so far. In this paper, recent OLED performance using our new blue phosphorescent material by vacuum process and the overview of solution processed OLED development are discussed.

| 高熱伝導ポリカーボネート複合材料 Thermally-Conductive Polycarbonate Compound |
井野 慶一郎 Keiichiro INO |
| ＜要旨＞ Polymer
materials have lower thermal conductivity than metal materials and ceramics.
Therefore, polymer materials are used as thermal insulations. Polymer
materials are used for various products because of excellent injection
moldability. These days, electronic devices are increasingly using highly
efficient semiconductors. Calorific value of an electronic device increases
with the miniaturization of semiconductors, and its high integration.
To maintain the performance of an electronic device, a sufficient cooling
system is required. For test results, the 6 mm interval of the radiating
fin - fin is desirable. Thermally conductive polycarbonate composite
has a thermal conductivity of 4.0 - 11.0 W/m・K. The effective range that performs heat conduction is 25 mm at the maximum, 25 mm height of a radiating fin is desirable. Around 3 mm thickness of a radiating fin is desirable, and around 5 mm thickness of the base cast by the side of a LED module is desirable to secure a heat current way, and for injection moldability. Keywords: Thermally / Conductive / Polycarbonate / Composite / Radiate / LED / Moldability |

| LED リフレクタ用耐熱性ポリアミド樹脂 Heat-Resistant Polyamides for LED Reflectors |
田村 興造 Kozo TAMURA |
| ＜要旨＞ Genestar™,
a PA9T-based heat resistant polyamide, is widely used as a reflector
for LED packages due to its good mold-ability, heat resistance, and light
resistance. We believe Genestar™ and its new polymer, with superior resistance against heat and light, will help
LED to be a standard light source for lighting applications. Keywords: LED Reflector / Polyamide / Heat Resistance / Light Resistance |

| 草や木からポリマー原料を生産する Transformation of Cellulosic Biomass into High-Value-Added Chemicals for Polymers |
原 亨和 Michikazu HARA |
＜要旨＞ Emerging
trends in chemical industry are prompting sustainable production of
useful chemicals, including polymers and new materials, from renewable
cellulosic biomass. This requires at least two chemical processes:
hydrolysis of cellulosic biomass into mono saccharides and tranformations
of monosaccharides into useful chemicals. However, efficient transformations
of cellulosic biomass and monosaccharides are no easy task. Here, we
demonstrate efficient cellulosic biomass transformation into heterocyclic
aldehydes by novel heterogeneous catalysts. |
