Goal and objectives of the project

Prepared high quality carbon nanotubes nanocomposite coatings for corrosion protection and weather resitance for carbon steels. Prepared hydrogen storage materials based on carbon nanotubes and LaNi5 containing capacity of 2% by weight.

Main results

- Theoretical results: Studied CNT oxidation process, modified CNT with magnetic iron oxide inhibitors by adsorption method.
+ The treated CNTs have purity above 99%, the specific surface area of 137m2/g and the hydrogen storage capacity up to 258mAh/g
+ The treated CNTs increase the hydrogen storage capacity of electrodes, the material consist of 90 % LaNi5 and 10% CNTs has the highest storage capacity, discharge capacity approximately 270mAh/g, equivalent to 1% by weight.
Apply results: Choosing the optimal ratio of 1% CNT in epoxy resin coating, studies physical properties, weather resitant and corrosion protection of coating containing oxidized CNT, CNT/Fe3O4, CNT modified silane and absorbing organic corrosion inhibitiors are very much higher than the coasting containing CNT unmodified. (Impact resitance: 200kg.cm, adhesion: 2.5 N/nm2, bending strength:1mm, take time reached 1000 hours salt fog)

Novelty and actuality and scientific meaningfulness of the results

- The project studied the oxidation surface CNT, modified CNT by the inorganic, organic compounds and physical adsorption of organic corrosion inhibitors.
- The project has been the research and manufacture of nanocomposite coatings anti corrosion protection and weather resistant based on CNTs modification
- The project has found out the optimal mixing ration for the LaNi5, alloy and CNTs to enhance the hydrogen storage capacity of the mixed material.
