The escalating global energy demand, propelled by rapid industrial expansion, has
underscored the imperative of transitioning to cleaner and more sustainable energy
sources to combat pollution and mitigate the adverse effects of global warming.
Triboelectric nanogenerators (TENGs) have emerged as a promising technology capable of
harnessing ambient mechanical energy and converting it into electrical power. This research
initiative seeks to advance the field by focusing on the development of composite materials
derived from a synergy of biopolymers extracted from natural sources, particularly
potatoes, and inorganic fillers.
The comprehensive objectives of this study encompass the extraction of biopolymers from
natural resources, the meticulous characterization of composite materials to ascertain their
mechanical, physicochemical, and morphological properties, the fabrication of TENGs
employing these composite materials, and an exhaustive evaluation of the TENGs'
performance metrics.
Remarkably, the composite materials exhibit outstanding dielectric properties,
characterized by exceptional dielectric permittivity (ε) values. At a fundamental level, these
materials showcase impressive dielectric constant (ε') values, with specific examples
reaching into the millions at a frequency of 1 Hz. Furthermore, the dielectric loss (ε'') values,
representing the imaginary component of permittivity, also exhibit notable characteristics.
For instance, certain composite materials demonstrate ε'' values that mirror the remarkable
ε' values, signifying their potential to excel in energy storage applications.
What sets this research apart is not only the development of materials with exceptional
dielectric properties but also the exploration of their practical application in triboelectric
nanogenerators. The TENGs fashioned from these composite materials consistently exhibit
remarkable voltage outputs, further underscoring their potential for various energy
harvesting applications.
