“…The metal oxide additives preserve their original characteristics during the heat treatment process, and the introduction of MWCNTs increased the conductivity of the composite material. Building on this work, Chen et al 83 prepared TPU/PAN/ Fe 3 O 4 composite nanofiber membranes by depositing Fe 3 O 4 onto a unique self-supporting electrospun TPU/PAN film via electrospinning and dip-coating processes. The obtained film shows a high magnetization intensity of 18.9 emu/g, and its SE in the X-band exceeds 30 dB.…”

“…The porous structure of the fiber, the magnetic loss effect of Fe 3 O 4 , and the dielectric loss effect of MXene result in outstanding EMI shielding performance of the composite fiber membrane with a thickness of 33 μm (SSE t = 9212.1 dB cm 2 /g). Chen et al 83 produced a unique TPU/ PAN self-supporting film via electrospinning and dipping processes. Subsequently, Fe 3 O 4 nanoparticles and MXene were deposited onto its surface to form a hybrid membrane.…”

The rapid development and popularization of smart and portable electronic devices have led to increasingly related electromagnetic pollution affecting human health and equipment safety. Thus, designing high‐performance electromagnetic interference (EMI) shielding materials with lightweight, flexible, and easy preparation is urgent. The intrinsic physiochemical properties of electrospun micro/nanofibers provide an attractive potential to ease and accelerate the next‐generation EMI shielding materials. Here, a detailed review of the electrospun EMI shielding materials is established. First, this article outlines the shielding mechanism of EMI shielding materials obtained via electrospinning. Then, the affecting factors of electrospinning process conditions on the resulting EMI shielding micro/nanofibers are discussed. Next, diverse fillers that contribute to the EMI shielding efficiency of electrospun materials are demonstrated. Finally, the conclusion and prospects are introduced, hopefully contributing to assisting with more comprehensive and rational designs of high‐performance electrospun fiber‐based EMI shielding for various applications. Priority measures and future directions are suggested for the future development of electrospun EMI shielding materials.

“…In the last two decades, nanotechnologies have been proposed in many fields. Their potentialities are extremely promising for a wide range of applications [ 1 , 2 , 3 , 4 ]. For example, carbonaceous nanofillers such as graphene-based nanoparticles, carbon nanotubes, fullerenes, etc., are extensively studied because of their peculiar properties, e.g., electrical conductivity and, thermal conductivity, that were previously limited to metals, attracting great attention from the industries in which these properties are strongly required [ 5 , 6 , 7 ].…”

Nanometric Mechanical Behavior of Electrospun Membranes Loaded with Magnetic Nanoparticles

This work analyzes on nanoscale spatial domains the mechanical features of electrospun membranes of Polycaprolactone (PCL) loaded with Functionalized Magnetite Nanoparticles (FMNs) produced via an electrospinning process. Thermal and structural analyses demonstrate that FMNs affect the PCL crystallinity and its melting temperature. HarmoniX-Atomic Force Microscopy (H-AFM), a modality suitable to map the elastic modulus on nanometric domains of the sample surface, evidences that the FMNs affect the local mechanical properties of the membranes. The mechanical modulus increases when the tip reveals the magnetite nanoparticles. That allows accurate mapping of the FMNs distribution along the nanofibers mat through the analysis of a mechanical parameter. Local mechanical modulus values are also affected by the crystallinity degree of PCL influenced by the filler content. The crystallinity increases for a low filler percentage (<5 wt.%), while, higher magnetite amounts tend to hinder the crystallization of the polymer, which manifests a lower crystallinity. H-AFM analysis confirms this trend, showing that the distribution of local mechanical values is a function of the filler amount and crystallinity of the fibers hosting the filler. The bulk mechanical properties of the membranes, evaluated through tensile tests, are strictly related to the nanometric features of the complex nanocomposite system.
