This study focuses on the simultaneous stiffening and percolating characteristics of the interphase section in polymer carbon nanotubes (CNTs) systems (PCNTs) using two advanced models of tensile modulus and strength. The interphase, as a third part around the nanoparticles, influences the mechanical features of such systems. The forecasts agree well with the tentative results, thus validating the advanced models. A CNT radius of >40 nm and CNT length of <5 μm marginally improve the modulus by 70%, while the highest modulus development of 350% is achieved with the thinnest nanoparticles. Furthermore, the highest improvement in nanocomposite’s strength (350%) is achieved with the CNT length of 12 μm and interfacial shear strength of 8 MPa. Generally, the highest ranges of the CNT length, interphase thickness, interphase modulus and interfacial shear strength lead to the most desirable mechanical features.

Geometrical Transformation

Molecular mechanics and dynamics have applied to study the behavior of single wall carbon nanotube bundles. A geometrical transformation of the nanotube cross section was observed when the tube diameter exceeded 1,4 nm where the cross section changed from circular to hexagonal. The elastic properties of the bundles were examined and shown to depend on the tube diameter but not on the geometrical transition. The interfacial shear strength between the adjacent tubes was estimated and shown to depend both on the diameter and on the geometrical transition.

In this paper, the “B” interphase parameter in the Pukanszky model and interphase strength for polymer carbon nanotube (CNT) nanocomposites are expressed by the critical interfacial shear strength (τc) and interfacial shear strength (τ) between a polymer matrix and CNTs.
