Abstract
Poly(vinylidene fluoride) (PVDF) is a versatile thermoplastic fluoropolymer with intriguing characteristics, which is receiving considerable attention from researchers in many areas. Recently, PVDF and its copolymer, such as poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) have been blended with ionic liquids to produce blend and composite materials for target applications. In this succinct review, two types of ionic liquids that are utilized for the preparation of PVDF and PVDF-HFP blends and composites, namely, hydrophilic and hydrophobic imidazolium-based ionic liquids, are reviewed. In addition, the effect of the ionic liquids on the physicochemical properties of the PVDF and PVDF-HFP blends and composites, is described as well. On top of that, a multitude of applications of the blends and composites are also succinctly reviewed. This review may give inspirations to the polymer blend and composite researchers in diversifying the applications of thermoplastic fluoropolymers through the utilization of ionic liquids.

Summary
These days, polymers can be tailor-made for specific applications, it can be done by chemically modifying the polymer functional groups and side chains [1]. Some polymers can physically be modified by utilizing ionic compounds, such as ionic liquids for target applications. Thermoplastic fluoropolymer, for example, poly(vinylidene fluoride) (PVDF) is blended with ionic liquids to produce blend and composite materials for a multitude of applications. PVDF is made from vinylidene fluoride monomer through a free-radical polymerization process. PVDF copolymer, such as poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) is blended with ionic liquids to produce blends and composites for a wide variety of applications. PVDF-HFP is made via copolymerization process by means of two different monomers [2].
