Results show that the long grafted chains and low reaction temperature help to improve the electrical conductivity of conductive composites.
So far, the resistor network model has been well documented [15] to predict the electrical conductivity of some conductive composites.
For (PANI-PPy)/SiO2 nanocomposite, the addition of SiO2 may increase the structure regularity of conducting polymers, so the electrical conductivity and thermal stability of conductive composites improve.
The strategy developed here can be extended to fabricate the 3D microstructured conductive composites by using other conducting polymers or water-soluble polymers.
Silicon nitride (Si3N4) processed with up to 25 vol.% of graphene nanoplatelets (GNPs) gives conductive composites with the highest electrical conductivity (40 Scm−1) reported for these ceramics with added conductive particles.
Generally, the metal with high electrical conductivity will become the choice of selection in producing conductive composites.
19c Cross-linked carbon black/PDMS conducting elastomer electrodes, 20a self-healing printable, stretchable and conductive composites of graphite nanoplatelets in silicone, 20b and ultra-stretchable conductors based on liquid metals and cross-linked thermoplastic elastomer gels 20c mark some developments in stretchable electrodes.
However, P3AT/inorganic conductive composites exhibit relatively poor thermoelectric performance because of their low electrical conductivity.
The small diameter, high aspect ratio, high conductivity, and mechanical strength of CNTs make them an excellent option for creating conductive composites for high-performance EMI shielding materials at low filling [13 17].
These fibers are highly stretchable and maintain metallic conductivity up to 700% strain, as shown in Figure 9. Stretchable, conductive composites often consist of solid conductors dispersed in elastomers and therefore undergo a trade-off between their ability to be stretched (favored by low solid content) and conductivity (favored by high solid content).
This could lead to advances not only in structural materials, but also in conductive composites.
