Oxygen-plasma treated graphene nanoplatelet (OGNP)/multi-walled carbon nanotube (MWCNT)/polycarbonate (PC) hybrid nanocomposites were prepared via melting process using a twin screw extruder. The content of OGNPs was in the range of 0-5.0 part per hundred of resin (phr) whereas the dosage of MWCNTs was kept constant at 2.0 wt%. Nanocomposites containing 2.0 wt% of MWCNTs and 2.0 wt% of MWCNT/1.5-5.0 phr of OGNP had tribo-charge voltages, surface resistivities, and decay times in the electrostatic discharge (ESD) specification. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) results showed that OGNPs slightly intercalated and distributed in the PC matrix. The glass transition temperature (Tg) and decomposition temperature (Td) of nanocomposites slightly changed as the content of OGNPs increased. The melt flow index (MFI) of nanocomposites significantly decreased when MWCNTs were added into the PC resin and slightly changed as the dosage of OGNPs was increased.

Graphene nanoplatelet (GNP) and multi-walled carbon nanotube (MWCNT) hybrid films were prepared with the aid of surfactant Triton X-100 and sonication through a vacuum filtration process. The influence of GNP content ranging from 0 to 50 wt.% on the mechanical and electrical properties was investigated using the tensile test and Hall effect measurement, respectively. It showed that the tensile strength of the hybrid film is decreasing with the increase of the GNP content while the electrical conductivity exhibits an opposite trend. The effectiveness of the MWCNT/GNP hybrid film as a strain sensor is presented. The specimen is subjected to a flexural loading, and the electrical resistance measured by a two-point probe method is found to be function of applied strain. Experimental results demonstrate that there are two different linear strain-sensing stages (0–0.2% and 0.2–1%) in the resistance of the hybrid film with applied strain. The strain sensitivity is increasing with the increase of the GNP content. In addition, the repeatability and stability of the strain sensitivity of the hybrid film were conformed through the cyclic loading–unloading tests. The MWCNT/GNP hybrid film shows promising application for strain sensing.
