| Abstract |
A strategy to enhance the energy conversion
performance of a cement-based triboelectric nanogenerator
(TENG) has been proposed for large-scale energy harvesting
from human footsteps. A cement-carbon black (CB) composite is
fabricated by incorporating CB nanoparticles with a hydroxyethyl
cellulose (HEC) admixture and used as a triboelectric material for
TENG. The fabricated cement-CB@HEC TENG exhibits a 13-
fold enhancement of the electrical output with the highest power
density of 2.38 W/m2. The tremendous improvement is ascribed
to a good dispersion of conductive CB nanoparticles in the cement
matrix, which is key for achieving a high dielectric constant that is
required to intensify the triboelectric charge density of TENG.
Moreover, it was found that the addition of the HEC admixture
plays a crucial role in not only providing a good dispersion of CB for generating dielectric polarization but also facilitating the
development of a microstructure and crystallization of cement hydration products to reduce the formation of air voids and
micropores. These factors synergistically contribute to the improved dielectric constant and compressive strength of the cementCB@HEC composite. This remarkable strategy presents great prospects for the development of smart cement materials for realizing
applications in large-scale energy harvesting toward sustainable, clean, and renewable energy sources. |
