Lightweight nanocomposites based on poly(vinylidene fluoride) and Al nanoparticles: Structural, thermal and mechanical characterization and EMI shielding capability

Abstract

Novel (nano)composites based on PVDF and different content of Al nanoparticles have been prepared in order to learn about their electromagnetic interference shielding capability. Very promising results are obtained, with an excellent balance between shielding and sample weight, so that these materials are potentially good alternatives to replace neat metals for that application. Moreover, a complete structural and morphological characterization, as well as an evaluation of their thermal and mechanical behavior, has been also performed.

The Addition of Aluminum Nanoparticles to Polypropylene Increases Its Thermal Stability

“…A similar increase was described by Lee et al [20] for a PP sample incorporating Pd nanoparticles. FTIR spectra have shown the existence of several interactions between a polyvinylidene fluoride matrix and Al nanoparticles in nanocomposites similar to the present PPAl5 [29]. These interactions can affect the mobility of poly mer chains and/or modify the E a of the degradation process.…”

Dielectric and Structural Properties of Poly(vinylidene fluoride) (PVDF) and Poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) Filled with Magnesium Oxide Nanofillers

“…840 cm -1 is a typical peak for either βor γ-phase crystals. A sharp and well-resolved band of 840 cm -1 observed in this spectrum indicates β-phase crystal of PVDF [28]. PVDF also showed a characteristic absorption band of well-defined α-phases at 612 cm -1 and 765 cm -1 .…”

Research into kinetic patterns of chemical metallization of powder­like polyvinylchloride

“…Such composites can be used as anti-static materials, flexible heaters, shielding materials from electromagnetic radiation, electrodes, sensors, etc. [8][9][10][11][12]. A significant group among these materials is made up of the metal-containing polymeric composites.…”
