Green and Flexible Electronics Based on Nanocellulose

Hirotaka Koga
Osaka University

Abstract: Wood-derived nanocellulose has become a major center of attraction as sustainable functional bionanomaterials, owing to its fascinating physical properties and renewability. Here, I will introduce nanocellulose-based electronic devices with high functionality, flexibility, disposability, and biodegradability, such as transparent conductive film, electronic paper, antenna, memory, and sensor.

Biography: Hirotaka Koga received his PhD from Kyushu University, Japan, in 2009 under the supervision of Prof. Takuya Kitaoka for paper-structured nanocatalyst composites for energy and environmental applications. He received Dean Awards for his sophisticated PhD thesis from Kyushu University in 2009. After JSPS postdoctoral study with Prof. Akira Isogai at the University of Tokyo, Japan, for cellulose nanofiber-based composite materials for catalytic and electronic applications, he moved to Osaka University, Japan, as a specially-appointed assistant professor in 2012, then promoted to associate professor in 2018. His recent interest is the material and structural design of paper by using advanced technologies, i.e., “renovation of paper”, for green chemistry and electronics. In 2016, 2017, and 2019, he was awarded Nature Industry Award, Young Researcher Award by the Cellulose Society of Japan, and The Young Scientists’ Prize, The Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology, respectively.
