CNT nanoparticles have high tensile strength, excellent thermal transfer properties, and optimal chemical and physical stability. The lack of CNT stable dispersion in most of the fluids limits its industrial exploitation in heat transfer applications. Researchers are constantly making efforts for preparing stable dispersions of CNT. Luckily, the unique πelectronrich structures of CNT open a ...

The main aim of this work is the fabrication of CuCNT nanocomposite powder using the MA by ball milling. The asreceived dendritic copper powders change their shape sequentially to flaky, disktyped particles and finally, to globular type particles. Also, the tendency of globular formation was prominent in the milled CuCu coated MWNTs (multi ...

The Crate performance of CNT and Super P was analyzed from to 5 C. In the first C and C, the capacity of CNT cell was slightly higher than Super P cell, and at 1 C both cells showed the same capacity as 147 mAh g −1. After 2 and 5 C, when the current density returns to 1 C, both cells returned their capacity.

1. Introduction Since the landmark paper by Iijima [1], carbon nanotubes (CNTs) have attracted great attention for structural and functional applications. Excellent mechanical, thermal properties along with high aspect ratio, large surface area and light weight, make CNTs become ideal reinforcement for composites [1], [2], [3], [4], [5], [6].
