Abstract

Interfacial properties are known to have a critical effect on the mechanical properties of a nanocomposite material system. Here, a Carbon nanotube/nylon 11 Nano Hybrid Shish-Kebab (NHSK) structure was used to enhance the interfacial load transfer in a CNT/nylon-11 composite. Characterization using differential scanning calorimetry (DSC) indicated that the polymer crystal in the NHSK has formed a more perfect crystal structure, while the overall crystallinity of the NHSK-nylon composite was found to increase when using the NHSK inclusions in comparison to the as-received carbon nanotubes (CNTs) studied as a control. Characterization of the different nanocomposite samples using Raman spectroscopy, with the samples heated to introduce stress via thermal expansion effects, found that the Raman shift at the D* band of the CNT in the NHSK-nylon 11 composite displayed a more pronounced change with increase in temperature, which is attributed to the NHSK structure being effective at transferring load from the nylon matrix to the nanotube reinforcement. These results suggest that this NHSK structure may be effective as a non-covalent approach to control the properties and interfacial behavior in carbon nanotube-polymer nanocomposites.
