“…Moreover, t is calculated to be 5.91 for σ AC and 4.13 for σ DC , which implies the formation of a 3D conductive network in the FSR matrix. Compared with our previous study, [ 40 ] when both CNTs and SiO 2 are added to the FSR rubber together, the resistivity and the electrical percolation threshold increased. The silica interrupts the conductivity network is dominant, and this may be advantageous for improving dielectric properties.…”

In this work, hybrid fillers consist of modified silica (SiO2) and multiwalled carbon nanotube (MWCNT) were used to improve the mechanical, dielectric, and thermal properties of fluorosilicone (FSR) composites via a direct mechanical mixing method. With the increase of CNT loading in SiO2/CNT hybrid loading ratio, the tensile properties, dielectric constant, electrical conductivity, and thermal properties all increase without a sharp sacrifice of flexibility. The dielectric constant of FSR‐S15/C5 achieved 7,370 @1 kHz, which is about four orders of the FSR‐S20, and the dielectric loss remains as low as 0.676 @1 kHz. Therefore, the linkage of SiO2 and FSR chains not only enhances the interfacial interaction between the fillers and FSR matrix but also decreases the agglomeration of the fillers in matrix. What is more, modified SiO2 and CNT were designed as the effective hybrid filler to improve the performance of the polymeric matrix through synergic effect.

“…19 MPa for a composite containing 7% graphene and 30% barium titanate. Regarding other carbonbased nanomaterials, such as multiwalled carbon nanotubes, Tang et al 11 reported percolation thresholds of 1.39 and 0.74 vol % for rubber composites prepared by direct mechanical mixing and solution-coagulation mixing, respectively. The superior results of the solution-coagulation mixing method were attributed to the more homogeneous dispersion of fillers in the matrix.…”

In this work, we develop fluorosilicone elastomer (FSE) compounds with advanced properties by incorporating graphene oxides functionalized with vinyltrimethoxysilane (GO-V) and allyl isocyanate (GO-A). The morphology and structure of the graphene oxides were characterized confirming the successful functionalization, with contents of functional groups of 9.80 and 3.60% for GO-V and GO-A, respectively. The strong elastomer–graphene oxide interaction accelerates the crosslinking reaction and causes an important enhancement of the mechanical properties and thermal stability of composites. In addition, the swelling resistance to acid, base, and organic solvents is improved by more than 30%. These functional properties make FSE/GO composites a promising new class of advanced materials, expanding their potential application in edge technologies, spanning the manufacture of automotive components, aerospace and aviation parts, oil, gas, and petrochemical components, among others, particularly, seals, gaskets, valves and pipelines, or different components exposed to oil or solvent and high temperatures that require higher performance compared to conventional FSE products.

“…By studying the differences in the mechanical properties of rubber-based and resin-based composites with fibers as reinforcements, it was found that in rubber-based composites, the improved bonding between the layers coupled with the flexibility were perhaps the major reason for the improvement in impact performance [34]. Adding conductive particles to the material could effectively improve the conductivity and resistive creep behavior of the rubber matrix composite [12,[35][36][37][38]. Some studies have also investigated the effect of fiber content and resorcinol-formaldehyde-latex (RFL) treatment on the chopped aramid fibers reinforced by acrylonitrile-butadiene rubber, finding that adding the aramid fibers effectively improved the wear resistance and the NBR composites via enhancing the hardness and tear strength.…”

Rubber-based conductive composites are widely used in sensors, wearable electronic devices and electromagnetic fields. In this work, by using the two-roll milling and hot-pressing process, chopped glass fiber (CGF) and graphene (Gr) as additives, and acrtlinitrile-brtadiene rubber (NBR) as the matrix, a series of anisotropic flexible rubber-based composites were prepared. Using this preparation method, both CGF and Gr additives were directly arranged in the material. When the content of CGF was 1 wt.%, the tensile strength in both the T and W directions of the material reached 27 MPa and 28 MPa, respectively. When the content of CGF was fixed at 1 wt.% and Gr was 1.5 wt.% and the elongation at break in both directions reached 328% and 347%. By focusing on the comparison of the dielectric differences in the T and W directions in the X band, it was found that the directional arrangement of the additives led to differences in the dielectric properties.
