Hybrid materials based on carbon nanotubes (CNTs) and polymers, which integrate the unique characters and functions of these two types of components, have shown improved properties and potential applications in many fields. However, the aggregation of CNTs in the polymer matrix is always a big problem in the preparation of composites. It has been proven that using CNT arrays instead of random C...

It is well known that the addition of carbon nanotubes (CNTs) can strongly affect the thermomechanical and electrical properties of the polymer into which they are dispersed. The common solvent mixing dispersion method of functionalized CNTs and polymer composites can improve thermal, mechanical, and electrical properties. In this study, functionalized single-walled CNTs (COOH-SWCNTs) and poly(...

The nanomechanical properties of carbon nanotubes particulate-reinforced aluminum matrix nanocomposites (Al-CNTs) have been characterized using nanoindentation. Bulk nanocomposite specimens containing 2 wt % multiwalled CNTs (MWCNTs) were synthesized by a combination of ball milling and powder metallurgy route. It has been tried to understand the correlation between microstructural evolution pa...

A novel class of carbon nanotube (CNT)-based nanomaterials has been surging since 1991 due to their noticeable mechanical and electrical properties, as well good electron transport properties. This is evidence that the development CNT-reinforced polymer composites could contribute in expanding many areas use, from energy-related devices structural components. As a promising material with wide r...

Abstract As a high-temperature thermoelectric (TE) material, ZnO offers advantages of non-toxicity, chemical stability, and oxidation resistance, shows considerable promise as true ready-to-use module under air conditions. However, poor electrical conductivity high thermal severely hinder its application. Carbon nanotubes (CNTs) are often used reinforcing phase in composites, but it is difficul...

Here, we present a review of recent developments for an off-lattice Monte Carlo approach used to investigate the thermal transport properties of multiphase composites with complex structure. The thermal energy was quantified by a large number of randomly moving thermal walkers. Different modes of heat conduction were modeled in appropriate ways. The diffusive heat conduction in the polymer matr...

Transition metal layered double hydroxides (LDHs) are one of the great potential electrode materials for pseudocapacitors. However, the aggregation and low conductivity of these metal compounds will constrain electrolyte ion and electron transfer and further affect their electrochemical performances. The nano-structured carbon coupled with the LDH matrix can act as an active component or conduc...

Supercapacitor (SC) is an energy storage technology that bridges the gap between conventional capacitors and rechargeable batteries. Emerging nano-architectured carbon–metal oxide composites are promising for electrode designs for supercapacitors due to their unique strategy utilizing electrochemical double-layer capacitance (EDLC) and pseudo-capacitance together in single cell to optimize the ...

High modulus of about 1 TPa, high thermal conductivity over 3000 W/mK, very low coefficient expansion (CTE), electrical conductivity, self-lubricating characteristics and density have made CNTs one the best reinforcing materials nano composites for advanced structural, industrial, strength wear-prone applications. This is so because it has capacity improving mechanical, tribological, electrical...
