Advanced materials for triboelectric nanogenerator

Abstract

Due to the advantages of excellent output power, low cost and easily preparation, triboelectric nanogenerator is developing rapidly in the field of renewable energy. The output performance of triboelectric nanogenerator is largely dependent on the surface charge density, which is closely related to the ability of the tribo-material to gain or lose electrons. To obtain higher output power, numerous efforts have been done on material modifications of the friction layer and electrodes of triboelectric nanogenerator with additional fillers or molecular modifications. In this review, advanced materials for the preparation of triboelectric nanogenerator devices to achieve high output, humidity-resisting and wear-resisting performance are presented and the working mechanisms of performance optimisation are discussed. Moreover, natural materials, recyclable materials and non-conventional electrode materials are mentioned to inspire subsequent research on triboelectric nanogenerator.

Advances in Multifunctional Sensors Based on Triboelectric Nanogenerator – Applications, Triboelectric Materials, and Manufacturing Integration

“…Among them, the commonly used polymer materials are PTFE, PVDF, FEP, Kapton, nylon, PDMS, Ecoflex, silicone rubber, and etc. [75][76][77][78][79][80][81][82] At initial stage of the development of TENG, polymer materials are usually used as thin films for simple operation, however, with more advanced technology have been introduced, fiber-like polymer materials have been fabricated for the manufacture of some textile-based TENG and wearable sensors.

Chemical–Mechanical Polishing of 4H Silicon Carbide Wafers

“…A mixed-abrasive slurry (MAS) contains two or more types of solid-phase abrasives, [91] including ZrO 2 /SiO 2 , nano-diamond/ SiO 2 , polymeric magnesium iron aluminum zinc silicate/ SiO 2 , SiO 2 /CeO 2 , and ZrP/Al 2 O 3 . [92][93][94][95][96] Compared with the single-abrasive slurry, a MAS exhibits better CMP performance. It has been found that adding 10 wt% diamond abrasives to SiO 2 slurry could increase the MRR from 60 to 600 nm h −1 and reduce the Ra from 68.3 to 0.55 nm.…”

Eco-friendly, compact, and cost-efficient triboelectric nanogenerator for renewable energy harvesting and smart motion sensing

“…The TENG output performance depends on triboelectrification contact and electrostatic induction between triboelectric materials [ 20 , 21 ]. Thus, this performance can be modified due to the surface charge density, contact area, thickness, and gap of the triboelectric layers and the operating frequency and force applied to the triboelectric materials [ [22] , [23] , [24] ].…”
