Compressive Buckling

This investigation focuses on the design of functionalization configuration at the atomic level to determine the influence of atomic structure on the mechanical properties of functionalized carbon nanotubes (F-CNTs) and their composites. Tension and compressive buckling behaviors of different configurations of CNTs functionalized by H atoms are studied by a molecular dynamics (MD) method. It is shown that H-atom functionalization reduces Young’s modulus of CNTs, but Young’s modulus is not sensitive to the functionalization configuration. The configuration does, however, affect the tensile strength and critical buckling stress of CNTs. Further, the stress-strain relations of composites reinforced by nonfunctionalized and various functionalized CNTs are analyzed.

Reinforced Mechanism

Carbon Nanotubes (CNTs) are functionalized with ethylenediamine by chemical cut and grafting process. CNTs/nylon-6 (PA6) composite is prepared by solution-evaporation method. The dispersivity of CNTs and mechanical properties of CNTs/PA6 composites are tested. Reinforced mechanism is also investigated. The results show that the ethylenediamine-functioned CNTs (s-CNTs) are well dispersed in the formic acid and the weight content of grafted ethylenediamine is about 30%. With only 2wt% addition of s-CNTs, the modulus, strength and strain of PA6 are dramatically improved by about 46%, 85%, and 200% respectively. The tensile course of s-CNTs/ PA6 composites shows that the increase of modulus were provided by both the increase of matrix crystallinity induced by s-CNTs and the recruitment of s-CNTs, and the improvements of strength and strain were attributed to the malleable integration between the s-CNTs and matrix, which was formed with s-CNTs, crystal matrix based on the tubes and the partial entanglements of tubes.
