Characterization of Reduced Graphene Oxide/Multiwalled Carbon Nanotubes/Polymer Nanocomposites Obtained By Laser Deposition

Abstract
In order to obtain hybrid reinforcement and to better utilize the extraordinary properties of graphene and carbon nanotubes, the researchers are focused on combining them. Most of the published papers explain that carbon nanotubes act as transverse bonds connecting the graphene platelets and forming a network around the polymer particle. As a result, a smaller percentage of hybrid reinforcement will be considered to improve the composite properties. The nanocomposites based on reduced graphene oxide, multiwalled carbon nanotubes and polymer matrix were synthesized by emulsion polymerization. Initial were prepared hybrids from reduced graphene oxide and carbon nanotubes in two different weight ratios 1:10 and 10:1. The goal of this research work was to make a comparison between the properties of the nanocomposites obtained by emulsion polymerization and laser ablation with IR CO2 laser. The obtained nanocomposites were characterized by several characterization techniques as: FTIR and UV/Vis spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), tensile testing, contact angle and surface energy measurements, and conductivity measurements.
