High-performance piezoelectric nanocomposite of poly(vinylidene fluoride-trifluoroethylene) with 2D crystalline ferroelectric chalcogel.

ABSTRACT: Ferro-piezoelectricity occurs in robust and ordered crystalline materials, where polarization is reoriented under an external field. However, complex electric fields, disordered networks, and porous materials with poor crystallinity hinder the development of high-performance ferro-piezoelectric materials. Here, we describe two-dimensional (2D) crystalline Na-Mn-Sn-S chalcogels ([Sn₂S₆]^4-:Mn²⁺ at a molar ratio of 1:0.5; NMSC-1) with a unique arrangement within a disordered network, resulting in unprecedented intrinsic ferro-piezoelectric characteristics. The NMSC-1 can be used as an efficient filler in poly(vinylidene fluoride-trifluoro ethylene) [P(VDF-TrFE)]/NMSC-1 nanocomposite, enhancing crystallization of P(VDF-TrFE) and its ferro-piezoelectr
