Nowadays, the efficiency enhancement of triboelectric nanogenerators (TENGs) is a big challenge, and one main factor in improving output performance TENGs enhancing electron affinities tribo layers. In present research, we investigated effect hyperbranched polyester first generation (HBP-G1) on tribonegativity poly(vinylidene fluoride) (PVDF) polymer. Initially, HBP-G1 was synthesized using pentaerythritol core dimethylol butanoic acid monomer facile single-step route characterized by FTIR NMR studies. Then, PVDF (PA0) its blended electrospun membranes with different weight percentages (5, 10, 15, 20 wt % as PA5, PA10, PA15, PA20) were fabricated traditional electrospinning technique. The morphological crystalline changes function examined SEM, FTIR, XRD analysis. such open circuit potential (VOC) short current (ISC) measured considering as-prepared tribonegative layers aluminum film tribopositive frictional Among combination PVDF/HBP-G1, 10 based (PA10/Al-TENG) exhibited maximum VOC 65 V (3 times that PA0) ISC 1.76 μA (2 PA0). TENG upon adding content to shows significance effect. Further, demonstrated energy harvesting applications illuminating LEDs powering low-power electronics (stopwatch) PA10/Al-TENG. proposed can be candidates for future self-powered wearable electronics.
