Flexible nanofiber separator based on a zinc metal-organic framework

Abstract

In this paper, a flexible composite of polyvinylidene fluoride (PVDF) and zinc-based metal-organic frameworks (MOF) was successfully designed and synthesized. This material can serve as a separator or active filter to trap gases or heavy metals in wastewater such as uranium. The fabricated sample is in the form of a nanofiber mat with doped MOFs created by electrospinning. The results show successful incorporation of MOF nanoparticles in the fibers. Measurement was performed using scanning electron microscopy, Raman spectroscopy and X-ray photoelectron spectroscopy. Novel PVDF@Zn-MOF nanofibers is a promising material that can have a great impact in the field of water treatment and solve environmental questions in developing countries.
