“…Although the electrospun materials are predominantly polymer based, certain amount of non-polymer contents (e.g., nano-sized fillers) can also be incorporated into the primary electrospinning solution to form hybrid ultrathin or nanocomposite fibers [ 11 , 12 , 13 ]. At present, the incorporation of GNPs has been achieved into electrospun fibers of poly(vinylpyrrolidone) (PVP) as a conductive additive to enhance the high-rate capabilities for lithium-ion batteries [ 4 ], polystyrene (PS) and polyvinyl chloride (PVC) to generate superhydrophobic surfaces [ 14 ], poly(vinyl acetate) (PVAC) to improve the optical absorption for ultrafast photonics [ 15 ], polyacrylonitrile (PAN) to produce carbon nanofibers (CNFs) [ 16 ], polyaniline/poly(methyl methacrylate) (PANi/PMMA) blends for conductive devices [ 17 ], and PAN/PVP blends as high capacitance materials [ 18 ].…”

Graphene nanoplatelets (GNPs) were synthetized from graphite powder and, thereafter, embedded in poly(ethylene-co-vinyl alcohol) (EVOH) fibers by electrospinning in the 0.1–2 wt.-% range. The morphological, chemical, and thermal characterization performed on the electrospun nanocomposite fibers mats revealed that the GNPs were efficiently dispersed and rolled along the EVOH fibrilar matrix up to contents of 0.5 wt.-%. Additionally, the dielectric behavior of the nanocomposite fibers was evaluated as a function of the frequency range and GNPs content. The obtained results indicated that their dielectric constant rapidly decreased with the frequency increase and only increased at low GNPs loadings while the nanocomposite fiber mats became electrically conductive, with the maximum at 0.5 wt.-% GNPs content. Finally, the electrospun mats were subjected to a thermal post-treatment and dark films with a high contact transparency were obtained, suggesting that the nanocomposites can be used either in a nonwoven fibers form or in a continuous film form. This study demonstrates the potential of electrospinning as a promising technology to produce GNPs-containing materials with high electrical conductivity that can be of potential interest in intelligent packaging applications as “smart” labels or tags.

“…The introduction of graphene, CNTs, and other types of carbon materials into the electrospun CNFs not only promotes the electrical conductivity, but also affects the overall architecture, hence boosting the electrochemical properties. Typical examples including graphene-beaded CNFs, [48][49][50][51][52][53][54] CNTreinforced porous CNFs, [55][56][57] graphene/CNT-embedded CNFs, 58 carbon black-doped porous CNFs, 59 and activated carbon nanowhisker-wrapped graphitized CNFs have been reported, 60 which show better capacitive performance than that of CNFs alone as described in Table S1. † However, only a slight increase in conductivity has been achieved by the incorporation of a conductive component into the CNF precursors.…”
