Abstract

The invention discloses a PDMS-PTFE film for improving the performance of a nano friction generator and a preparation method thereof, belonging to the technical field of friction nano power generation. The preparation method is as follows: by weight, take polydimethylsiloxane (PDMS) prepolymer and dissolve it in n-hexane, mix and stir, so that the two are fully mixed evenly; add PTFE emulsion to the mixed solution, and heat and stir to prepare Mixed solution; cool the above mixed solution to room temperature, add tetraethyl orthosilicate crosslinking agent, then add dibutyltin dilaurate catalyst, stir at room temperature to prepare a uniformly mixed PDMS solution to be solidified; then degas it; The solution is applied to the substrate of the nanogenerator, cured, and the film is peeled off from the substrate to obtain a PDMS-PTFE film. The present invention provides a method with simple process, low cost, and can be used for large-scale production to prepare PDMS-PTFE transparent flexible film for TENG, and provides a new method and idea for the production of high-performance TENG materials.

Description

technical field

[0001] The invention relates to the technical field of triboelectric power generation, in particular to a PDMS-PTFE transparent film for improving the performance of a nano triboelectric generator and a preparation method thereof. Background technique

[0002] As electronic devices and systems continue to evolve toward miniaturization, portability, and multi-function, a single electronic device often integrates many different types of sensors, and the construction of the Internet of Things is largely based on a large number of sensor units. network connection. Triboelectric nanogenerator (TENG), as an emerging energy conversion device based on electrostatic induction and triboelectric effect, can be used to directly collect human motion, mechanical vibration, sound wave energy and even raindrops that exist widely in nature and are not easily utilized. And the energy produced by ocean waves, etc., is therefore regarded as an effective way to realize green ene...
