Interrelation between Elastic Moduli of Filler and Polymethyl Methacrylate-Carbon Nanotube Nanocomposites

Abstract

The effect of ring-shaped formations of carbon nanotubes in a nanocomposite’s polymer matrix, which can be “open” and “closed,” on the nanocomposite’s elastic modulus is studied. It is demonstrated that we observe a rapid decrease of the filler’s elastic modulus at the transition from “open” to “closed” ring-shaped formations.
