“…Recently, developing polymer composites with enhanced electrical conductivity and dielectric constant (relative permittivity) has stimulated a surge in academic and industrial communities, due to their great potential in applications such as high-storage capacitors, electromagnetic shielding, and artificial muscles in electrostriction systems [ 36 , 37 ]. The use of carbon nanotubes (CNTs) and/or GNPs as the conductive fillers in polymer composites have been extensively studied [ 36 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ]. An electrical conductivity of 2.11 S/m was achieved by Zhang et al [ 55 ] with an addition of only 3.0 vol % of graphene into polyethylene terephthalate (PET).…”

Effects of Graphene Nanoplatelet Size and Surface Area on the AC Electrical Conductivity and Dielectric Constant of Epoxy Nanocomposites

et al. 2018

Epoxy nanocomposites reinforced with various grades of multilayer graphene nanoplatelets (GNPs) are manufactured and tested. The effects of size, surface area, and concentration of GNP, as well as alternating current (AC) frequency on the electrical and dielectric properties of epoxy nanocomposites are experimentally investigated. GNPs with larger size and surface area are always beneficial to increase the electrical conductivity of the composites. However, their effects on the dielectric constant are highly dependent on GNP concentration and AC frequency. At lower GNP concentration, the dielectric constant increases proportionally with the increase in GNP size, while decreasing as the AC frequency increases. At higher GNP concentration in epoxy, the dielectric constant first increases with the increase of the GNP size, but decreases thereafter. This trend is also observed for varying the processed GNP surface area on the dielectric constant. Moreover, the variations of the electrical conductivity and dielectric constant with the GNP concentration and AC frequency are then correlated with the measured interfiller spacing and GNP diameter.

“…The introduction of the layer modified the electrical properties of the composite, which exhibited electrical conductivity values of 0.008 S/cm and 0.0037 S/cm in plane and through thickness, respectively [ 84 ]. The coating of graphene oxide (GO) with conducting polymers, namely polypyrrole (PPy) and poly(3,4-ethylene dioxythiophene) (PEDOT) was studied as additional reinforcements to carbon fabric in C-fabric-epoxy composites [ 85 ]. Coated graphene was introduced into the epoxy and deposited on carbon fabric, then stacking these fabrics to form a composite by maintaining 60% volume fractions.…”

A Review of Multiple Scale Fibrous and Composite Systems for Heating Applications

et al. 2021

Different types of heating systems have been developed lately, representing a growing interest in both the academic and industrial sectors. Based on the Joule effect, fibrous structures can produce heat once an electrical current is passed, whereby different approaches have been followed. For that purpose, materials with electrical and thermal conductivity have been explored, such as carbon-based nanomaterials, metallic nanostructures, intrinsically conducting polymers, fibers or hybrids. We review the usage of these emerging nanomaterials at the nanoscale and processed up to the macroscale to create heaters. In addition to fibrous systems, the creation of composite systems for electrical and thermal conductivity enhancement has also been highly studied. Different techniques can be used to create thin film heaters or heating textiles, as opposed to the conventional textile technologies. The combination of nanoscale and microscale materials gives the best heating performances, and some applications have already been proven, even though some effort is still needed to reach the industry level.

“…Combining the addition of inorganic components with the chemical modification of the resin composition allows one to affect the properties of resulted material in a controlled manner. In the former case, inorganic particles or fibers are introduced into the composition of the material, thus improving the mechanical and thermal properties and decreasing the degree of swelling and solubility of the matrix [23,[28][29][30][31]. In the latter case, the chemical modification of the resin by organic reagents affects the supramolecular structure of the polymer.…”

Alumina nanofibers were prepared by sol-gel template method. Carbon nanofibers (CNFs) of feather-like morphology obtained by chemical vapor deposition of C 2 -C 4 hydrocarbons mixture have been used as a template. The distinctive feature of CNF is a friable disordered structure consisting of separate fragments of graphite-like phase. To simplify the sol-gel synthetic procedure, the impact of preparative conditions such as type of precursor and ratio of starting components was studied. CNFs were coated with corresponding alumina precursor and subjected to a high temperature treatment. The resulted alumina nanofibers were explored by means of scanning electron microscopy (SEM), physical nitrogen adsorption (BET), and X-ray diffraction. The optimal Al 2 O 3 :CNF ratio was found to be 1:6. According to SEM and BET, surface area of prepared alumina fibers 70-90 nm in diameter lies in a range of 149-174 m 2 /g. The thermal and strength properties of epoxy composites reinforced with alumina nanofibers are compared. It was demonstrated that used nanofillers affect noticeably the properties of the epoxy matrix. Graphical Abstract
