Polyvinylidene fluoride or polyvinylidene difluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. Its chemical formula is (C 2 H 2 F 2) n. PVDF is a specialty plastic used in applications requiring the highest purity, as well as resistance to solvents, acids and hydrocarbons.

聚偏二氟乙烯（英語： polyvinylidene difluoride ，简称PVDF）是一种高度非反应性热塑性 含氟聚合物 （ 英语 ： fluoropolymer ） 。其可通过1,1-二氟乙烯的聚合反应合成。PVDF具有多种商标名，如KF、Hylar、Kynar以及Solef。

PVDF (Kynar®) film offers excellent chemical and corrosion resistance, and features a high tensile strength (7,550psi@yield). It also has good thermal stability and can be used in sustained applications up to 300°F.

2016年7月6日 · This paper demonstrates a simple method for the preparation of poly(vinylidene fluoride) (PVDF) films using the antisolvent addition method.

PVDF Film (Kynar ® Film & Solef® Film) is both strong and tough as reflected by its tensile properties and impact strength. Compared to many thermoplastics, PVDF Film has excellent resistance to creep and fatigue, yet in thin sections such as films, PVDF components are flexible and transparent.

pvdf是一種含氟高分子材料，廣泛使用於耐候、抗紫外綫之塗層或薄膜。 本公司開發之PVDF薄膜更具備透明之特性，可進一步應用在光學照明等相關產業。

2022年9月19日 · High losses and low efficiency have been the main defects limiting poly(vinylidene fluoride) (PVDF) as an energy storage film capacitor material. Herein, the linear methyl methacrylate-co-glycidyl methacrylate (MG) copolymer was prepared to improve the dielectric and energy storage performance of PVDF.

FILM Kynar® PVDF Film can be used for applications requiring long-term protection. The film is produced by monolayer or multilayer technology as thin, thick, wide or narrow (from 10 to 175 µm), allowing great freedom of design. The commercial range in-cludes both mass-tinted and transparent films, which can be printed with a variety of designs.

Li et al. proposed a PVDF film–based bi-resonant structure device for piezoelectric energy harvesting, which can further improve the conversion productive efficiency from vibration to electricity by 40–85% significantly. Many other copolymers of PVDF were investigated by several researchers for energy harvesting applications.

PVDF - Film Polyvinylidene Fluoride, or PVDF is a highly non-reactive thermoplastic fluoropolymer a polymer of vinylidene floride. It is also known as KYNAR® (Arkema) or HYLAR® (Solvay Solexis).
