Poly(vinylidene fluoride) Nanocomposites

Abstract

This article overviews the current research trends in the field of electroactive polymer poly(vinylidene fluoride) (PVDF) composites with various nanofillers, such as clay, carbon nanotube, graphene, and inorganic nanoparticles. Here we give a concise account on the preparation and properties of different nanocomposites, highlighting some of their applications. Important aspects such as PVDF nanocomposite properties, morphology, structure, thermal stability, mechanical properties, phase transitions, crystallinity, conductivity, dielectric permittivity, piezoelectric polymorph formation, electromagnetic induction shielding etc. are discussed. Particular emphasis is given on the piezoelectric β‐phase formation and the subsequent improvement of mechanical properties, conductivity, dielectric permittivity, and electromagnetic shielding, which are of interest in the application of PVDF nanocomposites in both commodity and technological fields. Apart from the binary nanocomposites, ternary nanocomposites containing two nanofillers and their synergistic effect on PVDF properties are also discussed.

Impact of poly(ε‐caprolactone) on the thermal, dynamic‐mechanical and crystallization behavior of polyvinylidene fluoride/poly(ε‐caprolactone) blends in the presence of KIT‐6 mesoporous particles

“…A small shift in the frequency of carbonyl and CF 2 absorption bands was also observed for PVDF/PCL/KIT‐6 nanocomposites, which can be due to the formation of hydrogen bonds between the OH groups of the KIT‐6 surface and the electronegative groups of PCL and PVDF in addition to the specific interaction between the PVDF and PCL chains discussed earlier (Figure S2). In general, incorporating KIT‐6 nanoparticles into the PVDF/PCL matrix decreases the β ‐phase content and reduces the electroactive properties of the PVDF/PCL blend, which is contrary to the effect of some other Nano fillers like clays, TiO 2 , BaTiO 3 , graphene oxide and carbon nanotubes, reported in the literature 19,67 . According to the information in Table 2, there was no remarkable change in F ( β ) associated with incorporating 1 wt% KIT‐6 to the matrix.…”

Influence of Sodium Maghnite Nanoclay on the Polyvinylidene Fluoride Crystal Transition in Composite Membranes and Its Effect on Bovine Serum Albumin Protein Extraction

“…Indeed, it was found that NIPS casting method improved the β phase around 80%. More of research works have studied the possibility of composite membrane synthesis from combination between polymeric structures and different nanoclays varieties additives and their effect on membranes characteristics, Among the nanoclays types, Montmorillonite, Mg Fe layered double hydroxide modified Montmorillonite (LDH-Mt) and Cloisite were applied as nanofillers additives for the composite membrane manufacturing Multiple reasons are behind the choice of these nanomaterials as additives such as their abundances in the environment, high surface areas, porosity, possibility of intercalation and new energy portion during mixture with polymers structures caused by the electrical charge mobility [22]. Makwana et al [23] prepared matrix hybrid membrane based on PSF, PVP, Mt and LDH-Mt, the results showed the excellent contribution of nanoclays on the improvement of water permeability, fouling resistance and higher capacity for the separation of oil from water.…”

Polyvinylidene Difluoride: A Universal Binder for Preparation of Solid Phase Microextraction Devices

“…Fluorinated polymers 10 have been widely used in a large variety of practical applications, such as thermal coatings to increase the environmental durability of paints on surfaces, as ultrafiltration membranes in water purification, 11 as coatings in battery applications, 12 as architectural coatings, 13,14 electrical insulation, piezoelectric films for switches, sensors, and loudspeakers, among their many uses, due to their exceptional thermal and chemical properties, good adhesion, superior chemical resistance, impact resistance, corrosion resistance, abrasion resistance, heat resistance, and good flexibility. [15][16][17][18] Owing to their biocompatible nature, 18 fluorinated polymers have also been used for preparation of devices for environmental, bioanalysis, and biomedical applications. Given the many beneficial properties afforded by fluorinated polymers, applications related to these polymers have been extraordinarily successful in material chemistry.…”
