A research team led by Professor Xiao Changfa and Associate Professor Sun Guangwu (both serving as corresponding authors) from the Fiber Materials Research Center has published a paper in the top-tier journal in chemical engineering Chemical Engineering Journal (CAS Zone 1, IF=13.2). The work, supervised by the professors and conducted by postgraduate student Li Qianyue, is titled Bioinspired peacock-tail multilayer triboelectric nanogenerator based on highly-aligned fiber films.
This research is centered around the three core directions of flexible fiber materials: high-performance creation, process mechanism analysis, and intelligent manufacturing. Through bioinspired design and molecular-level structural regulation, the team successfully developed a triboelectric nanogenerator (TENG) that integrates an ultra-stretchability of 1600% with a high voltage output of 550 V, overcoming the key bottleneck in flexible electronics: the inherent difficulty in achieving both high electrical output and ultra-stretchability. Using this material, mechanical energy generated from clothing friction can be harvested and converted into electricity, which powers a set of small light bulbs arranged to display the English abbreviation of the university’s name on the back of the garment. In the future, this research can be extended to self-powered applications in smart wearable devices, promoting device miniaturization and lightweight upgrades, thereby effectively alleviating users’ battery life anxiety.
In addition, the research team also supervised postgraduate student Yang Yakun in publishing a paper titled Inverse prediction of micro-nano fiber membrane preparation process based on deep learning in Polymer (CAS Zone 2, IF=4.5), and guided postgraduate student Gao Ya in publishing a paper titled Modeling and characterization of nanoparticle-doped colloidal fibers under solution blow spinning in Langmuir (CAS Zone 2, IF=3.9).
The series of research outcomes not only provides a complete solution from molecules to devices for developing high-performance eco-friendly flexible electronic devices, but also promotes the transformation of fiber material preparation towards precision and intelligence. The related research was supported by the National Key R&D Program of China and the Hainan Provincial Natural Science Foundation.
