Electrical properties of structures based on varistor ceramics and polymer nanocomposites with carbon filler

The electrical properties of polymer nanocomposites with carbon nanotube fillers.

The electrical properties of polymer nanocomposites containing a small amount of carbon nanotube (CNT) are remarkably superior to those of conventional electronic composites. Based on three-dimensional (3D) statistical percolation and 3D resistor network modeling, the electrical properties of CNT nanocomposites, at and after percolation, were successfully predicted in this work. The numerical a...

Influence of Adding SiC on Microstructure and Electrical Properties of ZnO-based Nanocomposite Varistor

In this research the influence of adding SiC on microstructure and electrical properties of ZnO-based Nanocomposite varistors were investigated. SiC was added with amounts of 10-0 mass% to ZnO-based varistor composition. It is found that SiC allows reaching to high threshold voltage with formation of fine-graine...

The Electrical Properties and Conducting Mechanisms of Carbon Nanotube/Polymer Nanocomposites: A Review

This paper reviews the mechanism of the conducting process of carbon nanotubes (CNTs)-reinforced polymer nanocomposites. Comparison of the two different mechanisms, the formation of the conducting network and the hopping of the electrons, are discussed. The paper also describes the critical factors that determine percolation thresholds or the conductivity of the nanocomposites. By summarizing t...

Computational Micromechanics: Effective Electrical Conductivity of Carbon Nanotube-Polymer Nanocomposites

Nanocomposite development in the aerospace industry has been encouraged due to their considerable structural enhancements, particularly for material composed of carbon nanotubes included in a polymer matrix. In an effort to explore the nanocomposites’ material properties, previous works have made use of a computational micromechanics model for the analysis of the effective electrical conductivi...
