湿气发电纤维结构与性能研究进展OA

Moist-electric generation(MEG),an emerging clean energy harvesting technology,has attracted growing attention in recent years.The underlying mechanisms mainly involve streaming current and ion gradient diffusion.Owing to their lightweight,flexibility,and excellent weavabili-ty,MEG fibers hold great promise for wearable energy application.This review highlights recent advances in MEG fibers,with emphasis on three representative categories:carbon nanotube(CNT)-based fibers,featuring high electrical conductivity and mechanical flexibility,which enable considerable current output;graphene oxide(GO)-based fibers,which take advantage of abundant oxygen-containing functional groups and efficient ion transport to establish strong concentration gradients;and asymmetric-structured fibers,engineered through differential axial or radial gradi-ents of functional groups,effectively promote directional ion migration and thus significantly en-hance electrical output.Although there exist challenges in output performance,long-term stabili-ty,and textile-processing compatibility,MEG fibers show tremendous potential for smart tex-tiles,wearable electronics,and environmental monitoring,supported by advances in material de-sign,structural optimization,and device integration.
