From scientific and technological points of view, poly(vinylidene fluoride), PVDF, is one of the most exciting polymers due to its overall physicochemical characteristics. This polymer can crystalize into five crystalline phases and can be processed in the form of films, fibers, membranes, and specific microstructures, being the physical properties controllable over a wide range through appropriate chemical modifications. Moreover, PVDF-based materials are characterized by excellent chemical, mechanical, thermal, and radiation resistance, and for their outstanding electroactive properties, including high dielectric, piezoelectric, pyroelectric, and ferroelectric response, being the best among polymer systems and thus noteworthy for an increasing number of technologies. This review summarizes and critically discusses the latest advances in PVDF and its copolymers, composites, and blends, including their main characteristics and processability, together with their tailorability and implementation in areas including sensors, actuators, energy harvesting and storage devices, environmental membranes, microfluidic, tissue engineering, and antimicrobial applications. The main conclusions, challenges and future trends concerning materials and application areas are also presented.

Efficient dispersion of nanostructured fillers in thermoplastic polymers and elastomers remains an open challenge, and unless it is addressed, the potential utilization of conducting and magnetic fillers influencing the electronic properties of soft nanocomposites could not be properly assessed. Herein, we present a unique approach to address this challenge by constructing a microstructural fence using aligned magnetic networks of Ni nanowires in the direction of the applied external magnetic field, followed by flow-induced secondary in-planar alignment of multiwalled carbon nanotubes during the curing of the soft poly(dimethylsiloxane) (PDMS) elastomer. This mutually perpendicular arrangement offers unique magnetoconducting features to the soft elastomer matrix with moderately high conductivity, which is the key to superior electromagnetic shielding performance. The unique conformation of mutually perpendicular positions of both nanofillers in the bulk PDMS composites results in enhanced electromagnetic interference shielding performance (−28 dB) primarily through an absorption (80%) mechanism, driven primarily by the maximized interaction with incident electromagnetic waves inside the soft elastomer. Fundamental insights into the governing viscoelastic responses of these elastomer composites were gained through oscillatory rheological studies that investigate interparticle attraction within a quasi-solid network.
