Lumiflavine And Conductive Scaffold Construct Nanohybrid Organic Electrode

Lee, Minah, et al. Advanced Materials, 2014, 26(16), 2558-2565.

Active organic materials with aromatic redox centers are fixed to conductive scaffolds via non-covalent bonds, resulting in self-supporting and flexible nanohybrid organic electrodes. In this work, flavin molecules are used as models of redox active chemicals. Considering the gravimetric energy density, lumiflavine (LF), which has the smallest molecular structure among various flavin molecules, was selected as the active material. The results show that the synthesized nanohybrid organic electrode in the form of flexible self-standing paper has high energy and power density and excellent cycling stability.
Synthesis of nanohybrid electrodes
· A mixture of SWNTs (5 mg) and lumiflavine (4.5 mg) was added to acetone (20 ml). The solution was homogenized with an ultrasonic homogenizer for 10 min (2 sec on, 1 sec off), followed by sonication for 8 hours at 300 W intensity.
· Then, the solution was filtered through a Whatman Anodisc membrane of 0.1 µM pore size, followed by vacuum drying. The resulting interwoven and mechanically robust LF-SWNT film was easily removed from the membrane filter.
· The LF-SWNT film was directly utilized as the free-standing cathode without any further inclusion of binder, additives, and a current collector.
