Low-pressure air plasma-treated polytetrafluoroethylene surface for efficient triboelectric nanogenerator

In this study, an Al-PTFE triboelectric nanogenerator (TENG) that converts mechanical energy into electricity was investigated. The finite element analysis simulation was performed to illustrate the influence of surface engineering of the Al-PTFE TENG on electrostatic properties, especially at the e...
