Carbon nanotubes have unique characteristics:
100 times Stronger than steel
1000°С Thermal stability
1 million times The highest length to diameter ratio
5 times lighter than copper One of the best conductors in the world

Due to their properties, carbon nanotubes are genuinely the first universal additive that can be used to improve the performance of materials in various industries: Electrochemical power sources: lithium-ion batteries , Elastomers: tires and other rubber material , Polymer nanocomposite materials , Transparent conductive films .

Polymer nanocomposite materials


Despite their high cost, composite materials have become popular in industries where mechanical properties must go hand in hand with low weight and ability to withstand high loads. Composite materials are essential for today’s aerospace engineering, renewable power generation, automotive industry and construction. For example, the wings and fuselage of the new Boeing 787 Dreamliner are for over 50% made of composite materials, the exterior and the frame of BMW I3 are 70% made of carbon fiber reinforced plastic. The crucial factor determining the future of the “green economy” in the mass usage of composite materials is reducing emissions of CO 2, both in production and operation of composite-based products.

Polymer composites

Polymer composites are usually made of a plastic bases (called a matrix), which is reinforced with fillers of high strength, rigidity, etc. The combination of dissimilar materials, that’s what creates a new material, the resulting properties of which are different from those of each of its components.

The achievements in the CNT-industry have led to the emergence of a conceptually new generation of composite polymers. The use of single-walled carbon nanotubes as one of the components provided the results that seemed a miracle just yesterday. Increased strength and reduced weight, electrical conductivity, change in elastic parameters, heat resistance and other key physical and mechanical properties sometimes provide a tremendous economic impact.

Modification of properties of polymer composites through the uniquely high physical and mechanical characteristics of the nanotubes allows us to radically change the perception of building construction materials, new generations of vehicles and technologies in other areas.

Today more polymers are produced in the world than aluminum, copper, and all non-ferrous metals combined. Multiple applications of polymers require the enhancing of various properties and form a basis for further development of polymer composites.

Market of polymer nanocomposites

Sources: Transparency Market Research, 2013

The growth of the nanocomposites market is significantly higher than that of conventional polymers; the market volume in 2018 will be 3.5–5 times higher than the figures achieved in 2010.

Currently the share of nanocomposites produced by using carbon nanotubes does not exceed 10%. However, in the next 5 years the consumption of carbon nanotubes for the production of nanocomposite materials will significantly increase in volume.

By the year of 2020 the market of carbon nanotubes will grow more than 7 times, as compared to the indicators of 2013.

OCSiAl results

The flexural strength of a CFRP plate increases by 35% when adding 0.05% of TUBALL to the epoxy.

Epoxy resin with dispersed TUBALL. TEM image. OCSiAl 2014

Adding 0.08% of TUBALL to polyester resin makes SMC composite electroconductive and suitable for electrostatic painting.

Adding 0.05% of TUBALL to polypropylene increases its modulus of tension by 50% and its temperature of distortion by 15%.

Using TUBALL® as an additive increases strength, thermal and shock resistance by 30 to 50%. Adding TUBALL to polymers gives them electroconductive properties.

To reach the same results, hundred times more concentration of multi-walled CNTs is required, which may lead to significant complications in the production process or impossibility to manufacture products with MWCNT due to the increased prepreg viscosity and associated additional costs.

CFRP powered by TUBALL in collaboration with Zyvex Technologies

OCSiAl team working closely together with Zyvex Technologies Inc. is conducting R&D aimed at improving physical and mechanical properties of CFRP. Our goal is to make CFRP even stronger by incorporating small amounts of nanomodifier into it’s structure.

Adding 0.05 wt% of TUBALL additive into carbon fiber reinforced polymer, it’s physical and mechanical properties has increased substantially:

  • Tensile Modulus has increased at 32%
  • Flexural Strength at 35%
  • Flexural Modulus at 6%
  • Compression Strength at 20%

CFRP laminate composition: 2x2 Twill, 3K Warp, TR30 fiber, 198 gsm2 carbon fabric. Epon™ 828 epoxy resin (38%). Ethacure® 100LC curing agent. Conducted in accordance with ASTM standards.

These top-notch CFRP properties are achieved without changing current CFRP manufacturing conditions used in industry.

Differential scanning calorimetry (DSC) results show that cure kinetics of epoxy resin used in manufacture process of CFRP doesn’t change with introduction of TUBALL into the resin .

Along with simple dispersion process of TUBALL CNTs in CFRP epoxies this allows to introduce outstanding mechanical properties of TUBALL CNTs into many industrial applications.
