The electrically conductive, transparent, and flexible self-standing thin nanocomposite films based on copolyamide matrix (coPA:Vestamelt X1010) modified with 2D Ti3C2Tx (MXene) nanosheets were prepared by casting and their electrical, mechanical and optical properties and then, were investigated. The percolation threshold of the MXene filler within the coPA matrix was found to be 0.05 vol. %, and the highest determined electrical conductivity was 1.4 × 10−2 S·cm−1 for the composite filled with 5 wt. % (1.8 vol. %) of MXene. The electrical conductivity of the as-prepared MXene was 9.1 S·cm–1, and the electrical conductivity of the MAX phase (the precursor for MXene preparation) was 172 S·cm–1. The transparency of the prepared composite films exceeded 75%, even for samples containing 5 wt. % of MXene, as confirmed by UV spectroscopy. The dynamic mechanical analysis confirmed the improved mechanical properties, such as the storage modulus, which improved with the increasing MXene content. Moreover, all the composite films were very flexible and did not break under repeated twisting. The combination of the relatively high electrical conductivity of the composites filled with low filler content, an appropriate transparency, and good mechanical properties make these materials promising for applications in flexible electronics.

Metal alloys with low melting temperatures may be blended into polymers to improve their electrical conductivity. We review the preparation, morphology, and electrical conductivity of polymer composites based on low melting point metal alloys, with or without additional filler particles. Since such alloys can be liquid under melt processing conditions, the composite morphology is determined by phenomena such as coalescence of liquid metal drops, orientation of the liquid metal phase, or selective wetting of a second filler by the liquid metal. None of these phenomena appear in conductive composites based on more common conductive fillers such as carbon black, carbon nanotubes, or metal particles. The published literature suggests that composites based on low melting metal alloys, with or without additional non-melting filler particles, can have much higher percolation thresholds and much higher electrical conductivity (1,000 S/m) than those based on fillers such as carbon black or carbon nanotubes. Changes in other properties such as rheological or mechanical properties are also discussed. POLYM.

Conductive polymer composites of low melting point metal/ high melting point metal/polymer were prepared by melt mixing and investigated the effects of Sn‐to‐Cu content ratio on the microstructure and properties of Sn/Cu/PA6 ternary composites with a metal content of 53.3 vol %. The results show that Sn reacts with Cu to form intermetallic compounds during melting processing. When VSn/VCu is less than 1.5, the metal phase is a solid. However, if VSn/VCu is higher than 1.5, the metal phase is a suspension. As VSn/VCu increases, the morphology of metal phase changes from “islands” to physically continuous networks, and the Volume resistivity, impact strength and complex viscosity of the composites can reach 1.11 × 10−4 Ω cm, 3.8 kJ/m2 and 2.4 × 103 Pa s, respectively. Moreover, the resistivity of the composites with physically continuous networks is almost independent of temperature. The combination of low and high melt point metals can be considered as a useful strategy to prepare conductive polymer composites with high performance. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
