Large-Scale Nanofiber Manufacturing| Extreme environment-resistant highperformance triboelectric nanogenerator forenergy harvesting and self-poweredpositioning system

Prof. Caofeng Pan et al. from Beihang University (Nano Today, IF 13.2): High-performance triboelectric nanogenerator for extreme environments, enabling energy harvesting and self-powered positioning.

Challenge: Ensuring triboelectric device effectiveness under extreme temperatures is critical for global deployment of TENG-powered self-sufficient electronics, yet remains a significant challenge.

Approach: Prof. Caofeng Pan and Assoc. Prof. Ruirui Cao employed electrostatic spray-assisted electrospinning to fabricate thermally stable flexible PVDF-HFP/SEBS (PHSSO) composite membranes doped with stearic acid (SA) and octanoic acid (OA).

Innovation 1: Compared to original PHS membranes, PHSSO membranes exhibit not only enhanced triboelectric output but also maintain stable performance from room temperature to 60°C, demonstrating exceptional reliability and consistent power supply capability.

Innovation 2: The PHS1.5SO1.5 triboelectric membrane shows superior hydrophobicity, flexibility, stretchability, and cyclic stability. These properties make PHS1.5SO1.5-based TENGs ideal for self-powered positioning devices, providing adventurers and scientists with critical data (time/location) in extreme environments to ensure safety.
