Abstract

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 (Sc), intercalation degree, interphase depth (ti), 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. Sc=0.02 GPa increases the modulus of nanocomposites by 250 %, while Sc>0.13 GPa slightly improve the modulus by 30 %. Also, ti=10 nm and interfacial shear modulus (Si) of 100 GPa cause the 300 % improvement in the nanocomposite’s modulus, but ti<1.3 nm or Si<13 GPa slightly enhance the modulus by 10 %. Moreover, both the modulus and portion of networked clays straightly handle the modulus of nanocomposites. © 2021, The Korean Fiber Society for Fibers and Polymers and Springer.
