“…Among the various fillers, it is evidenced by previous research that the addition of graphene and its derivatives can effectively improve the physical properties of the matrix material, including pyroelectric performance. [21][22][23] Hsieh et al 24 developed the pyroelectric field effect transistor (FET) based on graphene-lead zirconate titanate (PZT) system. At an electric field of 6.7 kV/m, the current sensitivity of the photothermal FET could reach 360 nA/mW.…”

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.

The efficient degradation of organic pollutants in diverse environmental matrices can be achieved through the synergistic application of piezo‐catalysis and photocatalysis. The focus of this study is on understanding the fundamental principles and mechanisms that govern the collaborative action of piezoelectric and photocatalytic materials. Piezoelectric nanomaterials, under mechanical stress, generate piezo‐potential, which, when coupled with photocatalysts, enhances the generation and separation of charge carriers. The resulting cascade of redox reactions promotes the degradation of a wide spectrum of organic pollutants. The comprehensive investigation involves a variety of experimental techniques, including advanced spectroscopy and microscopy, to elucidate the intricate interplay between mechanical and photoinduced processes. The influence of key parameters, such as material composition, morphology, and external stimuli on the catalytic performance, is systematically explored. This study contributes to the increasing knowledge of environmental remediation and lays the foundation for the development of advanced technologies using piezo and photocatalysis for sustainable pollutant removal.
