Multiscale Theories and Applications: From Microstructure Design to Macroscopic Assessment for Carbon Nanotubes Networks

Abstract Carbon nanotube (CNT) networks enable CNTs to be used as building blocks for synthesizing novel advanced materials, thus taking full advantage of the superior properties individual CNTs. Multiscale analyses have adopted study load transfer mechanisms CNT from atomic scale macroscopic due huge computational cost. Among them, fully resolved structural features include graphitic honeycomb lattice (atomic), inter-tube stacking (nano) and assembly (meso) On an scale, elastic properties, ultimate stresses, failure strains with distinct chiralities radii are obtained under various loading conditions by molecular mechanics. The dependence cohesive energies on spacing distances, crossing angles, size edge effects between two is analyzed through continuum modeling in nanoscale. mesoscale models, which neglect structures but retain geometrical information about shape their into a network, been developed multi-level mechanism material deformation microstructural evolution stretching, elongation, strengthening damage failure. This paper summarizes multiscale theories mentioned above, should provide insight optimal assembling network materials elevated mechanical performance.
