US-based researchers have unveiled a stunning image of a polymer nanoflower designed for efficient electrodes in energy storage.
The poly (3,4-ethylenedioxythiophene) (PEDOT) structure was synthesized via hydrolysis-assisted vapour-phase polymerization using ethanol as a solvent.
In the image, the blue colour represents PEDOT, and the red colour represents iron oxide species that serve as a scaffold and assist in the growth of PEDOT nanostructures in situ during synthesis.
This coloured image depicts a poly (3,4-ethylenedioxythiophene) (PEDOT) nanoflower synthesized via hydrolysis-assisted vapor-phase polymerization using ethanol as a solvent.
Professor Julio M. D’Arcy from Chemistry in Arts & Sciences as well as the Institute of Materials Science and Engineering at Washington University in St. Louis imaged the structure with colleagues, while developing a simple method to fabricate the conducting polymer with a high surface area.
By combining vapour-phase synthesis with solution-based hydrolysis the researchers can synthesise 3D nanoflowers, 2D nanoplates and 1D nanofibres.
D’Arcy and colleagues believe this type of conducting polymer nanostructure is likely to be useful for energy transfer and storage applications.
