Abstract
Abstract Halide‐perovskite‐based mechanical energy harvesters display excellent electrical output due to their unique ferroelectricity and dielectricity. However, their high toxicity and moisture sensitivity impede their practical applications. Herein, a stretchable, breathable, and stable nanofiber composite (LPPS‐NFC) is fabricated through electrospinning of lead‐free perovskite/poly(vinylidene fluoride‐ co ‐hexafluoropropylene) (PVDF‐HFP) and styrene–ethylene–butylene–styrene (SEBS). The Cs 3 Bi 2 Br 9 perovskites serve as efficient electron acceptors and local nucleating agents for the crystallization of polymer chains, thereby enhancing the electron‐trapping capacity and polar crystalline phase in…
