Poly(vinylidene fluoride), PVDF, as one of important polymeric materials with extensively scientific interests and technological applications, shows five crystalline polymorphs with α, β, γ, δ and ε phases obtained by different processing methods. Among them, β phase PVDF presents outstanding electrical characteristics including piezo-, pyro-and ferroelectric properties. These electroactive properties are increasingly important in applications such as energy storage, spin valve devices, biomedicine, sensors and smart scaffolds. This article discusses the basic knowledge and character methods for PVDF fabrication and provides an overview of recent advances on the phase modification and recent applications of the β phase PVDF are reported. This study may provide an insight for the development and utilization for β phase PVDF nanofilms in future electronics.

“…They range from 21.4 μC/m 2 K for 55/45 to 10.6 μC/m 2 K for 80/20.

Organic ferroelectrics are increasingly important due to their complementary properties to classical, inorganic ferroelectrics. Flexibility, chemical resistance, scalability, high breakdown fields, and biocompatibility are attractive for many applications like energy harvesting and storage. The most known energy harvesting methods are piezoelectric, pyroelectric, and triboelectric. Here, we apply the well-established material's figures of merit to five polyvinylidenefluoride-based compositions ranging from ferroelectric to relaxor-like behavior to emphasize the importance of several key material parameters contributing to the maximal power output of energy harvesting devices. Afterward, we discuss the possibility of the same functional material storing the output energy for the development of scalable multifunctional devices.

“…When the content of diamond was 0.4 wt%, the pyroelectric coefficient reached a maximum of 87 μC/m 2 K, which was 3.5 times that of pure PVDF. Sagar et al 19 added barium zirconate (BaZrO 3 ) as a functional filler to PVDF matrix, and Tan et al 20 prepared pyroelectric films using zinc oxide (ZnO) and PVDF. Both the results showed that the pyroelectric properties of PVDF composite membrane could be moderately improved.…”

High pyroelectric performances of graphene nanoplatelet reinforced polyvinylidene fluoride composite film

As a semi‐crystalline polymer with pyroelectric properties, polyvinylidene fluoride (PVDF) has demonstrated great potential in developing smart and multifunctional materials. However, the low level of β phase in pure PVDF restricts its pyroelectric performance and applications. Selecting graphene nanoplatelets (GNP) as the reinforcing filler, this current work pioneeringly investigates the pyroelectric performances of GNP/PVDF composite films subjected to different scenarios. It is found that the addition of GNP can significantly enhance the formation of the β phase in PVDF and the pyroelectric performances of the composite. When the GNP content is 10 wt%, the pyroelectric coefficient of the GNP/PVDF composite film reaches up to 260 μC/m2K, which is about 10 times that of pure PVDF. Parametric study demonstrates that decreasing the thickness of the composite film and increasing the temperature are beneficial to improve the pyroelectric performances. Moreover, the addition of GNPs cannot only enhance the pyroelectric performance, but also improves the thermal stability of the composite film. The work is envisaged to provide guidelines for the design and manufacturing PVDF‐based sensors with improved sensitivity.
