Recently, the National Engineering Research Center of Rubber & Plastic Mold of ZZU has made new progress in the field of supercritical carbon dioxide foaming (scCO2) technology for the preparation of high-performance friction nanogenerators. The related results “Skinless Porous Films Generated by Supercritical CO2Foaming for High-Performance Complementary Shaped Triboelectric Nanogenerators and Self-Powered Sensors” were published in Nano Energy, a leading journal in the field of materials science. Ni Gaolei, a 2019 Master's student, is the first author of the paper, and Mi Haoyang, a top young talent of the Center, and Associate Professor Dong Binbin are co-corresponding authors.
