“…Additionally, with relation to Nylon-6 nanocomposites, hydrogen bond production results in a powerful interaction between the matrix and silicate layers. Maleic anhydride modified by propylene (PP-MA)/LS nanocomposites can also enable this behavior [64][65][66]. The tension at break increased dramatically in exfoliated Nylon-6 and intercalated PMMA nanocomposites.…”

“…Other studies [2,33,[51][52][53] have also observed that when the volume fraction of MWCNTs increases, then the distance between neighbouring MWCNTs decreases and this finally leads to reducing the electrical resistance and strain sensitivity (GF) of the nanocomposite. However, for a composite coated with adhesively bonded MWCNTs, there is no big obvious change in zones gauge factors.…”

Different methods have been used to deposit the Multi-walled carbon nanotubes (MWCNTs) onto the fibre surface to fabricate self-sensing composites. However, the constancy of the MWCNTs onto the fibre surfaces during infusion processing still unclear. In this study, we have deposited MWCNTs onto the glass fibre surface by two methods to investigate the state of MWCNTs during and after epoxy infusion processing. In the first method, the glass fibres were directly coated with the MWCNTs and in the second method, an adhesive was used to coat the glass fibre surface before depositing the MWCNTs over it. Rectangular specimens for both types of self-sensing composites were cut from different zones and then tested. The results showed that the self-sensing composites with adhesively bonded MWCNTs exhibited more consistent in their properties than the composites where no adhesive was used. In addition, the electrical resistance of both types of self-sensing composites was monitored during the epoxy infusion process. The results showed that the electrical resistance was no obvious affected for composite with non-adhesive bonded MWCNTs and was high for the specimens where the MWCNTs were not adhesively bonded. Moreover, the numerical study was also conducted and the results indicated that the relationship between the volume fraction of the MWCNTs and their tunnelling distance was an inverse. A recent study has proven that the properties of the self-sensing composites are strongly dependent on the method that used to deposit the MWCNTs on the surface of glass fibres layers.

“…However, it is challenging to use this type of films in industrial scales, such as applying to the surface of the inner pipe for heating purpose in order to lower the viscosity of the oil or petrol during transport. Additionally, in some applications, an enhanced of strength and ductility of the polymer is required in order to endure high applied loads, 18 which cannot be achieved by using epoxy matrix in self-heating nanocomposites. Therefore, nano-coating and flexible self-heating materials are not suitable for these applications.…”

Self-heating of nanocomposite materials based on the joule heating effect is suitable for numerous engineering applications. In this study, a highefficiency self-heating nanocomposite, using high conductive multi-walled carbon nanotubes (MWCNTs)-based phenolic resin, was fabricated with a hot press method. The microstructure and the thermal stability of self-heating nanocomposite were studied by X-ray diffraction, scanning electronic microscopy, and thermogravimetric tests. Electromechanical and thermal performance tests were conducted to investigate their potential as a self-heating application. Results showed that the compressive strength, modulus, and the piezo-resistive behaviour were higher after adding MWCNTs to the phenolic resin, indicating better load transfer and self-damage sensing as well. Moreover, at 4.0 wt% of MWCNTs concentration, the electrical conductivity of a self-heating nanocomposite showed a higher value of 13.26 S/m which was also found to be proportionally increased with the thickness of the samples, it was ≈25.5 and ≈12.8 S/m for 10 and 3 mm, respectively. In addition, a steady-state temperature of ≈110°C could be reached at low applied volts (8 V) as well as its heating performance was significantly dependent on the input power and the thickness of the sample. This is also confirmed by statistical results between the sample with thicknesses of 3 and 10 mm in terms of power consumption with P value ≈ .0001. Furthermore, the influence of Joule heating was estimated analytically based on the one-dimensional heat transfer equation in companying with other previous models. The estimated distributed temperatures values were in good agreement with the experimental results. The selfheating nanocomposite described in this study has the potential to be used in various industrial applications and a wide range of sectors due to its ability to self-damage sensing, easy fabrication, and high heating efficiency at low power consumption.
