With the support of the China Scholarship Council and the National Natural Science Foundation of China, Associate Professor Yang Lili from our School of Transportation has made significant progress in the field of composite electrode materials. During her visit to the University of Pennsylvania, she collaborated with Professor Yang Shuo, a researcher at the university, and achieved promising results in this area.
Recently, the two researchers co-authored an article titled "In-situ Preparation of a Single-Walled Carbon Nanotube/Polyaniline Nanoribbon Aerogel for Self-supporting, Flexible Energy Storage Devices," published in *Chemistry of Materials*, a prestigious journal by the American Chemical Society. The paper, which carries an impact factor of 8.238, quickly gained attention from both researchers and editors. It was among the top three most downloaded articles of the month and was even featured on the journal’s official Twitter account.
In recent years, the development of composite electrode materials based on carbon nanotubes has become a hot topic in material science. However, creating a structure that combines carbon nanotubes with other nanoactive materials while maintaining flexibility, self-supporting properties, and high performance remains a major challenge.
The research team successfully developed a composite aerogel using single-walled carbon nanotubes and ultra-thin, long polyaniline nanobelts. This material forms a bicontinuous and interpenetrating network, which enhances ion and electron transport efficiency. The three-dimensional nanopore structure also promotes rapid electrolyte infiltration, making it highly suitable for flexible energy storage applications.
These findings offer new insights into improving energy storage performance and have potential applications in road sensing systems, wearable electronics, and biomedical devices. The study highlights the growing importance of functional materials in transportation and beyond.
Yang Lili, who earned her Ph.D. in Materials Science and Engineering from our university in 2009, has been a faculty member since 2010. She became an associate professor in 2012 and a doctoral supervisor in 2014. Her research focuses on new functional materials and microstructures, particularly their application in traffic-related fields such as roads, vehicles, and traffic signs.
So far, she has published 20 SCI-indexed papers, with a cumulative impact factor exceeding 41.5. In addition to her work on energy storage materials, she has also collaborated with Yang Hao on research involving transparent hydrophobic (oil-repellent) coatings and biomimetic traffic warning materials. These innovations aim to improve vehicle antifreeze performance, surface deicing, and anti-fouling capabilities.
Their collaborative efforts have been published in reputable journals such as *Particle and Particle System Characterization*, *Chemical Communications*, and *Materials Chemistry Frontiers*. Their ongoing research continues to push the boundaries of functional materials in real-world applications.
