Abstract:
Balsa wood, a naturally occurring material that is renewable and environmentally friendly has
undergone delignification protocol. Flexible electrodes play a pivotal role in the
development of wearable electronics, enabling conformable and adaptable
interfaces for comfortable user interactions and various biomedical applications.
Fossil fuels, although once the cornerstone of global energy, now face increasing
scrutiny due to their environmental impact, spurring efforts towards cleaner,
renewable energy sources and technologies. In this work, nanofibers composites
including reduce graphene oxide (rGO), polypyrrole (PPy), and polyvinyl alcohol
(PVA) as rGO/PPy are deposited on balsa wood template using an easy, low-cost,
and sustainable approach which is the electrospinning technique. Nanofibers
composites were characterized by Fourier transform infrared spectroscopy (FTIR),
X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman
spectroscopy and electrochemical measurements CV, GCD, EIS done by Corrtest
workstation (China). The highest specific capacitance is 52mF/g was obtained at
0.05mA current density. The redox peaks in CV show its hybrid nature so prepared
flexible electrode which is derived from balsa wood is suitable and reliable for
hybrid supercapacitors.
