Summary: This study focuses on the conductivity model of carbon nanotubes (CNTs)-reinforced polymer nanocomposites (PCNTs), considering the roles of interphase and tunneling sections and introducing an expanded Takayanagi equation. Experimental data show good agreement between the model predictions and real specimens. Several factors, such as filler loading, percolation onset, and CNT volume fraction, influence the conductivity of the nanocomposites.

Summary: A theoretical model is proposed to predict the electrical conductivity of polymer samples containing silver nanowires (AgNWs). The model takes into account the roles of interphase and tunneling regions, waviness and dimension of AgNWs, and network size and conductivity of the sample. Experimental data from various samples are used to validate the model, which shows good agreement with the measured data. The model investigates the effects of different parameters on electrical conductivity and can be used to estimate the conductivity of polymer nanocomposites in future research. It can also be applied to optimize the performance of biosensors for detecting breast cancer cells.

Summary: A new simplified finite element analysis method is proposed to predict the electrical and strain response probability of graphene composites. The dispersion of agglomerates enhances the electrical properties of composite materials, while the size distribution of fillers has a negative impact on the electrical properties. These results are important for the evaluation and design of graphene composites as sensing materials in flexible sensors.

Summary: This paper simplified the Hui-Shia model to evaluate the electrical conductivity of CNT-reinforced nanocomposites, considering factors such as CNT aspect ratio, network structure, interphase depth, and tunnels between CNT. Long CNT and dense interphase improve conductivity, while short CNT and sparse interphase reduce it. Both short and wide tunnels are desirable for controlling the conductivity of nanocomposites.

Summary: The study investigates the frequency dependence of the conductivity and electric modulus of silver/polyacrylonitrile nanocomposites, revealing a power law relationship between conductivity and frequency, as well as the impact of interfacial polarization on the imaginary part of the electric modulus. The frequency dispersions of conductivity and electric modulus are well described by the Dyre and Cole-Davidson models, allowing for the estimation of relaxation times and activation energies. The proposed mechanism of charge transport in nanocomposites involves the presence of Ag-4(2+) and Ag-8(2+) silver clusters within the polymer.

Summary: In this study, the effects of single-walled carbon nanotubes (SWCNTs)/poly(3,4-ethylene dioxythiophene) poly(4-styrene sulfonate) (PEDOT:PSS) composite-treated cotton on the transparency and conductivity of pure cotton were systematically investigated using a four-probe stack made of copper (Cu). The composite cotton exhibited a surface resistance of 0.08 ohm/cm, which remained stable even after 3 months. Various characterization techniques, such as X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC), were employed to evaluate the structural, morphological, and thermal properties of the composite cotton. The results suggest that cotton fabric has great potential for applications in smart wearable textiles and supercapacitors.
