Abstract

The challenges in the complex structure and preparation method for triboelectric nanogenerators (TENGs) currently hinder their widespread application. In this study, the thermoplastic polyurethane (TPU) foam-based single-layer TENGs were developed. The excellent dispersion of carbon nanostructure (CNS) in TPU improves the cell structures, dielectric constant and conductivity of TPU foams. The cell size reaches 4.15 μm and the dielectric constant of TPU foam increases from 12 to 4678. The improved dielectric properties and conductivity of TPU foams enhance the output performance of single-layer TENGs. The maximum output voltage of the TPU foam-based single-layer TENGs is 15 V. The short-circuit current of the TENGs reaches 90 nA. This work presents a TPU foam-based TENGs characterized by a simple structure and straightforward preparation process.

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
