Effect of electro-magneto mode number on CNT/GNP polymer composite quantum tunneling

Abstract

Highly sensitive thermoresistive composites have great potentials for preventing overheating in electronic devices. Electro-magneto influenced mode numbers have a major effect on the quantum tunneling which has a critical role in electronic applications. A numerical model considering the electrical tunneling effect between carbon nanotubes (CNTs) and graphene nanoplatelets (GNPs) is developed to describe the electrical resistance change induced by mechanical deformation. The multistep percolation model scheme is based on separation distances and surged tunneling proposed to temperature change. The temperature-dependent quantum tunneling and fillers’ movement account for various parameters, such as CNT dispersion, temperature coefficient of resistance and physical properties. Comparisons between results for applied magnetic field suggest an improved conductivity for intensified magnetic field. Moreover, thermoresistivity declares a linear decrease with temperature, in which the highest thermo-resistive sensitivity was measured for highly aligned CNTs reporting a TCR of −0.004 °C. © 2025 The Korean Society for Composite Materials and IOP Publishing Limited.
