One-Step Coaxial Electrospinning of PS/BTO@PVDF Core–Shell Nanofibers for Double-Layered TENGs with Ferroelectric-Enhanced Charge Storage Layer
Published 2025“…Although numerous studies have presented novel methods to enhance the TENG performance by incorporating functional intermediate layers, complex multistep fabrication processes pose challenges for practical applications. In this study, polystyrene (PS)/BaTiO<sub>3</sub> (BTO)@polyvinylidene fluoride (PVDF) core–shell nanofibers (NFs) were developed through a one-step coaxial electrospinning process, simplifying fabrication while significantly increasing the energy conversion efficiency of the TENG. …”
