■タイトル
 Molecular modification and application of bio-based polybenzimidazole as stable polymer electrolyte

■論文概要
 Conventional bio-based plastics are usually low performance plastics in terms of thermo-mechanical properties. We have successfully synthesized bio-based plastic consist of high thermo-mechanical properties comparable with engineering plastics. Polybenzimidazoles (PBIs) are a series of super high performance polymers attracting researchers' attention because of PBIs have a rigid aromatic structure and hetero rings in their backbone to induce a good stability. However, previously bio-based PBIs have ever been tried to prepare and base on such a background we have used renewable 3-amino-4-hydroxybenzoic acid (3, 4-AHBA) derived from Actinomycetes metabolite to produce bio-based PBI. Also, PBIs have active imidazole hydrogen (-NH) to receive chemical modification. Here we report N-boronation of the PBI via lithiation to be ionically conductive. The PBI was modified by triethylborane substitution to imidazole proton to create boronated PBI (B-PBI) with Li counter ion. Considerable battery performance was confirmed along with stable interfacial properties while using this as solid polymer electrolyte (SPE).

■受賞にあたって一言
 It's always a privilege to have a chance of presenting your research as oral presentation on such a big platform like-"MoDeSt 2018" while some other senior researchers didn't get such opportunity other than poster presentation. Moreover, I am thankful to MoDeSt society and organizing committee for awarding me the "MoDeSt grant" and registration fee waive off. I would like to convey my sincere gratitude to Professor Tatsuo Kaneko for his continuous support, motivation and constructive guidance. I am also immensely grateful to Professor Noriyoshi Matsumi and Prof Raman Vedarajan for their necessary guidance. Lastly I would like to thank all of the Kaneko lab members for their support.
