POLYMER APPLICATIONS

ApNano Nanutubes under microscopeNanoMaterials’ inorganic nano-particles can be incorporated into polymer matrices to increase their strength and fracture toughness, and enhance their tribological and thermal properties.

NanoMaterials’ multi-layered WS₂ nano-particles tackle one of the key problems of carbon nano-tubes, which is high rates of defects and agglomeration that translate to problematic dispersability.

Due to their low defect concentration, high uniformity and unique morphology, NanoMaterials’ multi-layered WS₂ inorganic fullerenes and nano-tubes demonstrate excellent dispersability in various polymer matrices.

Nano-composites based on multi-layered WS₂ inorganic fullerenes and nano-tubes demonstrate enhanced properties in small quantities. This performance boost takes place thanks to the enormous interface area between the dispersed nano-particles and the matrix.

Polymer composites graphWS₂-enhanced composite materials feature unique properties such as:

  • Low brittleness and increased fracture toughness
  • Ultra high strength and modulus
  • Low light scattering

These characteristics, along with their extreme pressure (EP) anti-friction and anti-wear properties, make NanoMaterials’ nano-particles promising candidates for incorporation in superperforming composite materials.

Some properties demonstrated by such materials include:

  • Superior fracture toughness, shear and peel strength in epoxy matrix composites and adhesives
  • Increased elastic modulus of PMMA fibers along with increased strength and fracture toughness
  • Enhanced crystallinity and glass-transition temperature in various polymers
  • Improved dispersion of carbon nano-tubes in thermoplastics

NanoMaterials’ inorganic fullerenes and nanotubes can be applied for reinforcing bulk polymers and adhesives (thermoplastics and thermosets) for various applications. Such nanoparticles will enhance the matrix’s impact absorption, strength and elasticity, as well as its resistance to friction and wear.
