Prediction of Youngs modulus of bamboo-like carbon nanotubes based on MMT/FEA
INTRODUCTION Since their discovery carbon nanotubes have attracted considerable attention in scientific communities. This is partly due to their remarkable mechanical, electrical and thermal properties. There are many products with varied topography during the synthesis of carbon nanotubes (CNTs) due to different synthesis methods and experiment conditions. The bamboo-like CNTs structures with many long hollow compartments, a kind of defect CNTs, were typically 10nm in diameter and a few micrometers in length. Due to the hollow compartments, the bamboo-like CNTs possess bigger specific surface area than the ideal CNTs. The over properties bring off the application of bamboo-like CNTs in adsorption and storage of gas (e.g. H2) ,nanoreactor, catalyst carrier and reinforcement of composite and so on . In this paper, the mechanical property of bamboo-like CNT was investigated by molecular mechanics theory combined with finite element analysis (MMT/FEA). The element parameters using in FEA were obtained from the known C-C bond parameters.
