Abstract
The droplet triboelectric nanogenerator (D-TENG) converts mechanical energy into electricity through contact electrification and electrostatic induction at the liquid–solid interface. The device’s efficiency is significantly influenced by the surface molecular structure of its triboelectric layer. By applying a fluorosilane surface modification, we enhanced the contact electrification sites and improved electron transfer between water molecules and the triboelectric layer, leading to a high-performance D-TENG. This modification allowed the surface potential of modified PTFE to reach 85% of its maximum with just five droplets, generating maximum charges of 80 and 500 nC with deionized and tap water droplets, respectively. These results surpass those of similar energy harvesting devices. The successful electron transfer mechanism was confirmed through first-principles and molecular dynamics, suggesting our approach could be broadly applicable to improving other triboelectric nanogenerators.

期刊介绍:
ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format.
ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology.
The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
