The mechanical properties of oxygen plasma-treated carbon nanotube and silicon dioxide-reinforced polytetrafluoroethylene composite film

Abstract

The aim of this work is to evaluate the effects of oxidation treatment and the addition of silicon dioxide (SiO2) on the mechanical properties of carbon nanotube (CNT)/polytetrafluoroethylene (PTFE) composite film. A powder impregnation process with integrated inline continuous oxidation of CNTs was used to produce CNT/PTFE composite. CNT/PTFE composite was processed into test laminates by compression molding, and interface-dominated composite properties were studied. The tensile strength of composites-containing SiO2 and oxidation-treated CNT improved obviously.
