Role of Polytetrafluoroethylene Material in the Field of Triboelectric Nanogenerator
In today’s fast growing world human beings are quite busy and depend on electronic machines for their routine work. However, these machines work on batteries which need to be charged from time to time. Objectives: Again disposal of batteries when fully exhausted is also one of the biggest troubles. In this paper, the newly developed triboelectric energy harvesting technique is discussed, which converts mechanical energy into electrical energy and works on the principle of triboelectrification and electrostatic induction. Triboelectric nanogenerator (TENG) has a limitation of low output current which depends on the surface charge density of tribo material. This paper emphasizes the use of Polytetrafluoroethylene (PTFE) material which has high electronegativity of all the tribo electric material. Methods: This study emphasizes on different techniques used for improving the performance of the PTFE based TENG such as friction reduction, multilayer integration and hybridization with a piezoelectric generator. Novelty: In this paper different technique of improving the performance of triboelectric nanogenerator is discussed. Findings: Output performance of the PTFE based TENG can be further improved by combining different techniques.
