“…This evidence legalizes the developed model, because both interphase thickness and strength reveal the interaction/adhesion at polymer -nanoparticles interfacial area. [43,44] The grafted CNT provide the strong bonding on the chitosan producing the strong interphase properties, but the poor interfacial adhesion between chitosan and MWCNT in chitosan/MWCNT sample weakens the interphase aspects. The effective interphase strength is also calculated using Equation (13) as 65.9 and 286 MPa for the examples.…”

The operative interphase properties surrounding carbon nanotubes (CNTs) networks are applied to progress a simple and applicable simulation for the strength of nanocomposites. Both critical interfacial shear strength (τ c ) and interfacial shear strength (τ) define the operative depth and power of interphase area. The experimental results of selected examples and the parametric analyses are employed to accept the established model. The experimental data properly fit to the model's forecasts and all parameters reasonably affect the nanocomposite's strength. Very low τ c (10 MPa) and extremely high τ (400 MPa) significantly improve the strength of nanocomposites by 700%, while τ c > 43 MPa slightly increase the nanocomposite's strength. The strongest and the densest interphase around CNT nets can raise the strength of nanocomposites by 450%, but very poor or thin interphase only changes the nanocomposite's strength by 10%. Additionally, the narrowest and the biggest CNT produce the sturdiest samples, while thick CNT (CNT radius > 11 nm) cannot strengthen the polymer media.

“…It should be noted that a high concentration of interphase zone demonstrates the strong interfacial interaction, which positively reinforces the samples. [45,55] The desirable effects of interphase concentration on the mechanics of nanocomposites were mentioned. [56][57][58] Therefore, the established model correctly correlates the relative modulus to interphase concentration.…”

In this work, we focus on the minimum interfacial shear modulus (S c ) and interfacial shear modulus (S i ) controlling the efficiency of interphase zone in polymer clay nanocomposites, since the stress transferring through interphase section handles the stress bearing of samples. The roles of "S c " and "S i " in the effective thickness and concentration of interphase zone are clarified. Moreover, a model based on Kolarik system is developed for modulus of clayreinforced nanocomposites, which reflects the efficiency of interphase zone. The experimental data of tensile modulus for many samples display good matching with the predictions of the advanced model. Also, all model parameters properly manipulate the nanocomposite's modulus. Thick clay (t > 4 nm) cannot generate the interphase zone in the samples. A poor "S c ," high "S i ," and thin clay improve the modulus of nanocomposites, but very high "S c ," extremely poor "S i ," or thick clay cause a poor nanocomposite. A high value of S c = 0.21 GPa deteriorates the reinforcing efficiency of clay in nanocomposites. Furthermore, low S i < 35 GPa produces a poorer nanocomposite than the polymer matrix. Additionally, complete exfoliation of thin clay (t = 1 nm) causes 900% improvement in the nanocomposite's modulus.

“…It is also shown that the interphase strength improves by thin interphase indicating the inverse relation between interphase strength and thickness, while both interphase thickness and strength directly correlates to the extents of interfacial interaction/adhesion between polymer matrix and nanoparticles. 55,56 So, eqn (23) is not appropriate for the interphase strength in CNT nanocomposites.…”

“…However, the thickness and strength of interphase region in nanocomposites depends on the interfacial adhesion between polymer matrix and nanoparticles. 55,56 In other words, the strong interfacial interaction between polymer matrix and nanoparticles produces the thick and strong interphase. Therefore, the interphase strength directly depends on the interphase thickness approving the calculations of developed equations.…”
