Abstract
To enhance the piezoelectric capabilities of the β-phase of poly(vinylidene fluoride), a new composite membrane was prepared via electrospinning. This consist of Bi2ZnB2O7 and poly(vinylidene fluoride). A comparison of electrospun and composite fibers showed a significant increase in β-phase content. XRD and FTIR were used to characterize the samples' structures. FE-SEM and HR-TEM were also used to examine sample morphology. The optical properties of the BBZO-PVDF membrane were further assessed using UV–visible diffuse reflectance spectroscopy. The composite membrane's effectiveness was tested using photocatalysis, piezocatalysis, and photo-piezocatalysis. Methylene blue (MB) dye was degraded by these methods. The synergy between light and piezoelectric actions improved degradation performance significantly. It achieved a 74% degrading efficiency and a kinetic rate constant of 7.3 × 10−3 min−1. The findings show that the BBZO-PVDF composite membrane has great potential for enhanced environmental remediation and catalytic processes.
