Triboelectric polymer with excellent enhanced electrical output performance over a wide temperature range

Advances in high‐temperature operatable triboelectric nanogenerator

“…Moreover, our group has conducted relevant and significant research in this field. 120,121 Our efforts culminated in the design of a groundbreaking thermo-regulating TENG (Tr-TENG) that leverages phase change materials (PCMs) to mitigate the thermal negative impact of PTMs and maintain high-temperature steady electrical performance, as depicted in Figure 9A,B. 120 The Tr-TENG is composed of a sheath/core electro-spun fiber membrane and conductive elastic fabric, enabling the simultaneous harvesting of both mechanical and thermal energy.…”

“…83,[122][123][124][125] In light of this, our group employed blade coating technology to fabricate a series of fatty acid (FA)-doped PVDF-HFP (PH-FA) PTM films with optimized ratios, as depicted in Figure 9H. 121 Here, the FA was utilized to enhance the electronegativity of PVDF-HFP PTM and simultaneously employed as lubrication additive to improve the wear resistance. As shown in Figure 9I-K, the PH-SA PTM exhibited exceptional electrical output characteristics with V T /V Room , I T /I Room , and Q T /Q Room (output efficiency) values at 100 • C reaching unprecedented levels of 231.10%, 251.46%, and 234.01% respectively, which have not been reported in previous studies related to PTM-TENG.…”

Enhanced nanogenerator by embedding lead-free double perovskite Cs2AgBiBr6 in polymer matrix for hybrid energy harvesting

“…Various methods have been proposed for composite film preparation, including electrospinning, 34 one-step co-precipitation, 23 and blade coating technology, 35 etc. Rather than the above tedious processes, the CABB–PVDF based composites were prepared by spin-coating with additional drop-casting in this work to form a HENG device using CABB as the effective filler material.…”

Rotary Wind‐driven Triboelectric Nanogenerator for Self‐Powered Airflow Temperature Monitoring of Industrial Equipment

“…[20][21][22][23][24][25][26][27][28][29] Moreover, regarding hot airflow energy harvesting, several methods for modifying triboelectric materials to break through wind-driven TENG's working temperature limitations has been reported. [30] For instance, Tao et al proposed a fluorinated polyimide film with doped BaTiO 3 nanoparticles demonstrating high surface charge density (200 μC m −2 ) and thermal charge stability. [31] The feasibility of activesensing of physical parameters, including wind speed, and direction was also reported.…”
