ZnONWs with uniform morphology (mean diameter: 36.5 nm) are successfully synthesized and characterized. FTIR analysis confirms that incorporating bCNTs into PVDF significantly enhances the beta-phase content, while adding ZnO NWs (1-10 wt.%) resulted in progressive intensification of beta-phase characteristic peaks, with higher ZnO content showing stronger electroactive phase formation. The optimized composition (PVDF/0.5 wt.% bCNTs/5 wt.% ZnO NWs) demonstrates superior piezoelectric performance with a power density of 5.62 mu W cm-2, voltage output of 1.55 V, and current output of 14.48 mu A. Moreover, the composite exhibits excellent mechanical properties with a tensile strength of 48 MPa and maintains stable performance under cyclic loading. The enhanced performance is attributed to the synergistic effect between bCNTs and ZnO NWs, optimal beta-phase formation, and efficient charge transfer pathways. This study demonstrates the potential of melt-mixed PVDF nanocomposites for practical energy harvesting applications.eninfo:eu-repo/semantics/openAccessbranched carbon nanotubeselectrical outputmelt mixingnanomaterialspiezoelectric nanogeneratorPVDF nanocompositesZnO nanowiresArticle10.1002/mame.2025001223109WOS:0014998377000012-s2.0-105007243407Q2Q1
