NOVELTY - Stabilizing carbon oxide nano-tube suspension by graphene involves using suspension containing liquid medium, solid particles and stabilizer. The liquid medium comprises distilled water, solid particles comprise carbon nano tube, and graphene is used for obtaining stabilizing agent by electrochemical deposition in potassium hydroxide electrolyte solution. The carbon oxide nano-tubes are added to suspension of stabilizer as graphene nanoparticles. The nano-graphene particle suspension has particle size of 30-70 nm and obtained by placing in rotary homogenizer with power of 4kW for 5 minutes. The lead electrode is dipped in carbon nano-tube suspension, then added 55 wt.% sulfuric acid, where mass ratio of the suspension is 200C/kg, current density is 25-30mA/cm2, carbon nano-tube is washed by distilled water having pH of 6.5-7. USE - Method for stabilizing carbon oxide nano-tube suspension by graphene used for manufacturing composite material, shielding electromagnetic radiation, preventing radio interference, developing antistatic and anti-friction coating, manufacturing temperature, pressure and humidity sensor. ADVANTAGE - The method stabilizes carbon oxide nano-tube suspension without low conductivity impurity, prevents the suspension from layering into each independent phase, stabilizes the suspension in the component of the obtained suspension, and does not use surfactant solution, and effectively used for 30 days or more under the condition of no surfactants.

The carbon oxide nano-tubes are added to suspension of stabilizer as graphene nanoparticles. The nano-graphene particle suspension has particle size of 30-70 nm and obtained by placing in rotary homogenizer with power of 4kW for 5 minutes.

The lead electrode is dried for 20 seconds at 800℃, then the carbon nano-tube after oxidation is added into the graphene for 10 minutes, when the concentration of the suspension of the graphene is 0.25g/l, further 7.5g carbon oxide nano-tube, and 5 g or 10 g carbon oxide nano-tube added, when the concentration of the graphene of the nano-particle is 0.5g/l.
