Effect of Imperfect Interphase Section Neighboring Dispersed and Networked Nanoclay on the Modulus of Nanocomposites by a Modeling Method

In this work, we highlight the flawed interphase section surrounding dispersed and networked nanoclay to simulate the stiffness of polymer nanocomposites. The proposed model undertakes the crucial interfacial shear modulus (S-c), intercalation degree, interphase depth (t(i)), percolation onset, clay portion in the networks and the modulus of interphase zone around clays. Many experimental data from literature and parametric examines are utilized to approve the established model. S-c=0.02 GPa increases the modulus of nanocomposites by 250 %, while S-c>0.13 GPa slightly improve the modulus by 30 %. Also, t(i)=10 nm and interfacial shear modulus (S-i) of 100 GPa cause the 300 % improvement in the nanocomposite's modulus, but t(i)S(i)<13 GPa slightly enhance the modulus by 10 %. Moreover, both the modulus and portion of networked clays straightly handle the modulus of nanocomposites.

Automated summary

In this study, a model is proposed to simulate the stiffness of polymer nanocomposites, focusing on the flawed interphase section surrounding dispersed and networked nanoclay. Experimental data and parametric examines validate the established model. The modulus of nanocomposites is influenced by various factors, including interfacial shear modulus, interphase depth, and clay portion in the networks.
