With the support of the China Scholarship Council and the National Natural Science Foundation of China, Associate Professor Yang Lili, a young teacher at the School of Transportation of our school, cooperated with Prof. Yang Shuo, a researcher at the University of Pennsylvania during his visit to the University of Pennsylvania, and obtained new research on composite electrode material preparation. Achievements.
A few days ago, the two parties co-authored an in-situ preparation of a single-walled carbon nanotube/polyaniline nanoribbon aerogel on the Chemistry of Materials, a well-known journal organized by the American Chemical Society. A self-supporting, flexible energy storage device" article (influence factor 8.238). The article received great attention from researchers and editors. The number of downloads was ranked in the top three of the periodical during the month, and it was recommended by the journal's official tweets.
In recent years, the preparation of composite electrode materials based on carbon nanotubes has attracted much attention. However, how to construct a composite structure of carbon nanotubes and other nano-active materials to achieve the self-supporting, flexibility, and high performance of electrode materials at the same time is still plaguing most scientific research. A difficult problem for people.
The composite aerogel formed by the single-walled carbon nanotubes and the ultra-thin and long-long polyaniline nanobelts prepared by this research has a bicontinuous and interpenetrating network structure formed by the conductive material and the active material, which is not only beneficial to the ion/electron efficiency Transmission, and three-dimensional connectivity of the nanopore structure facilitates the rapid infiltration of electrolyte ions. The research results provide new research ideas for improving the storage performance of energy storage materials, and can also be applied to road sensing systems, wearable electronic products, biomedical devices and other related equipment to provide high-performance flexible energy storage electrodes.
Yang Lili, 32 years old, received a Ph.D. in materials science and engineering from our university in 2009. She stayed in school in 2010 and was named associate professor in 2012 and doctoral supervisor in 2014. She is mainly engaged in the research of new functional materials and microstructures, and is committed to the application of functional materials in traffic areas such as roads, vehicles, traffic signs, etc. She has published 20 SCI retrieval papers with a cumulative impact factor of 41.5.
In addition to the study of energy storage materials, Yang Lili and Yang Hao also collaborated on the research of transparent hydrophobic (oil-repellent) coatings and traffic warning materials based on biomimetic structures that can be used to improve the antifreeze and surface deicing performance of vehicles and antifouling of vehicles. The relevant collaborative research results have been published in the journals such as Particle and Particle System Representation, Chemical Communications, and Materials Chemistry Magazine C.
