Outline of Final Research Achievements

Novel method for preparation of transparent conductive polymer/carbon nanotube composites utilizing photo-induced bond dissociation was investigated. Influence of electric conductivity and dispersion/aggregation state of carbon nanotubes in the composites was also examined. It was found that the transparent conductive composites can be made by employing hydroxyl ammonium chloride as a dispersant of carbon nanotubes. However, it was also found that dispersion of carbon nanotubes was suppressed with the UV-induced bond formation, and the electric conductivity was consequently lowered compared with the unirrdadiated samples. Fabrication of durable and highly conductive polymer/carbon nanotube composites will be a subject for further study.

Academic Significance and Societal Importance of the Research Achievements

本研究では、光化学反応によるポリマー/カーボンナノチューブの結合形成を用いて透明導電材料を作製する方法を検討した。ポリマー中でカーボンナノチューブを分散させる方法を新たに見出したことで、透明導電材料作製技術の一端に貢献したと考えている。また、ポリマーとカーボンナノチューブとの化学結合の形成が材料の電気伝導性に及ぼす影響についても調べ、化学結合形成が電気伝導性を低下させる影響を及ぼすことを見出したが、このことによって材料の耐久性と電気伝導性を両立させるために検討すべき事柄の手がかりが得られたと考えている。
