Mechanical Properties of Elastomeric Terpolymer Composites Containing Carbon Nanotubes

Abstract

Nanocomposites were obtained by mixing terpolymer and carbon nanotubes (CNTs) in a twin-screw extruder at 135–155°C. The results indicated that increasing the amount of PSt, the molecular weight of PSt macromonomer of terpolymers and CNTs charged resulted in improving the tensile strength and modulus at 300% elongation of nanocomposites.

^a TS, denotes tensile strength; UE, Ultimate elongation, M, modulus at 300% elongation; PS, permanent set.

^b Nanocomposites made from terpolymers containing PSt macromonomer with a molecular weight of 1.79 × 10⁴ and CNTs (3.5% based on total mass of terpolymers).

^a Composites made from copolymers with mass ratio of PSt macromonomers: BA:AA = 30.7:66:3.3 and 3.5% CNTs (based on total mass of terpolymers).

^a Composites made from the terpolymers obtained by terpolymerization at mass ratio of PSt macromonomer (Mn = 1.79 × 10⁴): BA:AA = 30.7:66:3.3 and 3.5% CNTs (based on total mass of terpolymers).
