Possibility of Using Nanoparticle-Loaded Polyester Fibers as a Triboelectric Generator
Abstract:
This study aimed to present a method for measuring the mechanical strength and electrical chargeretention properties of fibers containing nano-sized oxide particles, which have become widely usedin recent years, and to clarify the fundamental physical properties of these fibers. There have beenfew studies measuring the mechanical and electrical properties of composite fibers containing nanosizedoxide particles. Polyester fibers containing SiO2 and ZrO2 nanoparticles were fabricated usingindustrial techniques to clarify the effect of particle introduction on strength. Furthermore, theelectrostatic charge properties of fibers containing these particles, which act as insulators, weremeasured, revealing that mechanical strength and electrical charge retention properties are mutuallyexclusive parameters. Increasing the nanoparticle content decreased mechanical strength, butprolonged the charge half-life and improved electrostatic retention. Furthermore, it was shown thatthis phenomenon can be represented using an equivalent circuit model of a resistor and a capacitor.
