Polyamide 4.6 has excellent properties, such as high temperature resistance, crystallinity, fatigue resistance, melting temperature, excellent creep resistance, toughness, and good wear properties, but low thermal conductivity values. For this reason, its use in thermal applications has been limited. In this study, its use in thermal applications can be increased by increasing its thermal conductivity with carbon-based fillers and reinforcements added to the PA46 structure. The aim of this study is to examine the carbon fiber (CF), synthetic graphite (SG) and graphene nanoplatelet (G) loading on the mechanical, thermal, physical, and electrical properties of polyamide 4.6, which are produced using co-rotating twin-screw extrusion. Tensile and flexural strength of polyamide 4.6 increased with the addition of CF at all weight fractions. The highest electrical conductivity value was measured as 4.01 S/cm in PA46-20CF-20SG-3G composite material. The highest in-plane thermal conductivity achieved in this study at 20 wt% CF, 20 wt% synthetic graphite, and 5 wt% graphene loading was 20.43 W/mK. However, the highest through-plane thermal conductivity value was obtained to be 4.19 W/mK at 20 wt% CF. Graphene and synthetic graphite are more efficient to increase the inplane thermal conductivity, while CF is more efficient to increase the throughplane thermal conductivity.

“…GO and rGO with many oxygen functional groups are more popular than pristine G, because they can be easily homogeneously dispersed in different polymer matrices. However, in order to achieve better dispersion, several surface modifications of G, GO, and rGO have been done [ 75 ]. In this regard, Park and his coworker [ 79 ] synthesized two different polyimide (PI) composites using rGO and reduced iodo phenyl functionalized GO (r-I-Ph-GO) with various content (0.5, 1, and 2 wt.%) by using an effective method of in situ polymerization.…”

“…G;GO;rGO/Polymer Composite G-derivatives/polymer-based composites have attracted great attention for the fabrication of chemiresistor sensors due to their high sensitivity, long reliability, and low power consumption [74]. They have been synthesized using various methods with superior electrical and mechanical properties compared to pure polymers, which have been reviewed by Lawal and Alshamaileh [75]. As mentioned before, the preparation and dispersion method of nanofiller into polymer matrices influences the properties of polymer nanocomposite.…”

Composites of organic compounds and inorganic nanomaterials provide novel sensing platforms for high-performance sensor applications. The combination of the attractive functionalities of nanomaterials with polymers as an organic matrix offers promising materials with tunable electrical, mechanical, and chemisensitive properties. This review mainly focuses on nanocarbon/polymer composites as chemiresistors. We first describe the structure and properties of carbon nanofillers as reinforcement agents used in the manufacture of polymer composites and the sensing mechanism of developed nanocomposites as chemiresistors. Then, the design and synthesizing methods of polymer composites based on carbon nanofillers are discussed. The electrical conductivity, mechanical properties, and the applications of different nanocarbon/polymer composites for the detection of different analytes are reviewed. Lastly, challenges and the future vision for applications of such nanocomposites are described.

“…Graphene coated CF reinforced polymer composites are used due to graphene’s exceptional electrical, thermal, and mechanical properties [ 98 , 99 , 100 ]. Numerous studies have been done by incorporating graphene or graphene oxide (GO) sheets onto a wide range of polymer matrices [ 98 , 101 , 102 , 103 ]. He et al [ 104 ] have introduced the graphene/CF hybrid as a multi-functional interfacial nano-reinforcement of CF reinforced polytetrafluroethylene composites for the enhancement of the mechanical and electrical properties.…”

Carbon fibre reinforced polymer composites have high mechanical properties that make them exemplary engineered materials to carry loads and stresses. Coupling fibre and matrix together require good understanding of not only fibre morphology but also matrix rheology. One way of having a strongly coupled fibre and matrix interface is to size the reinforcing fibres by means of micro- or nanocarbon materials coating on the fibre surface. Common coating materials used are carbon nanotubes and nanofibres and graphene, and more recently carbon black (colloidal particles of virtually pure elemental carbon) and graphite. There are several chemical, thermal, and electrochemical processes that are used for coating the carbonous materials onto a carbon fibre surface. Sizing of fibres provides higher interfacial adhesion between fibre and matrix and allows better fibre wetting by the surrounded matrix material. This review paper goes over numerous techniques that are used for engineering the interface between both fibre and matrix systems, which is eventually the key to better mechanical properties of the composite systems.
