Novel molecular designing of solid polymer electrolytes of bio-polybenzimidazole with ultrahigh conductivity
Here we have successfully synthesized bio-based plastic consist of high thermo-mechanical properties comparable with engineering plastics. Polybenzimidazoles (PBIs) are a series of highest thermo-stable 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 lithium single-ion conducting polymer electrolyte using organoborane-modified polybenzimidazole (B-PBI) and ionic liquid (IL). 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).
First of all it was an honor for me to present my research outcomes as poster presentation in a conference like-NMS-XIV, co-organized by the 'International Union of Pure and Applied Chemistry' (IUPAC). I could meet with enormous number of researchers from China and many other countries who are working on the same field as mine. Moreover, I am thankful to organizing committee to consider my research for the excellent poster prize. I would like to convey my humble gratitude to Professor Tatsuo Kaneko for his continuous support, guidance and encouragement. I am also immensely grateful to Professor Noriyoshi Matsumi and former Asst. Prof. Raman Vedarajan for their necessary guidance. Lastly I would like to thank all of my lab members for their continuous support.
