Nanomaterial technologies

Nanoparticles offer unique properties and features due to their small size. However, their strong tendency to aggregate in solution presents several challenges such as a loss of difficulty in processing and handling. Effective dispersion, stabilisation, and functionalisation of nanoparticles has therefore become a critical factor in obtaining the performance required from the market for applications such as Multi-layer Ceramic Capacitors (MLCCs) for compact electronics, as well as in other nanocomposite materials.

Enabling high performance nanomaterials

To address these challenges, we offer a range of solutions to improve the properties and performance of sub-micron particles, in polar, non-polar and aqueous systems, including both organic and inorganic particles of different chemistries.

These nanomaterials which we support include:

  • barium titanate
  • carbon nanotubes (CNTs)
  • conductive carbon
  • graphene, graphene oxide, reduced graphene oxide and silver

Key benefits of our additives for nanomaterial formulations

  • Improved dispersion & solid loading for resource efficiency
  • Low viscosity for consistent and easily handled pastes, slurries, and dispersions
  • Improved compatibility of nanoparticles with polymeric matrices
  • Applicable with broad range of solvents
  • High purity and clean burn out

Particle size

Particle size distribution affects consistency and functionality of nanomaterials. In this example, a dispersion of titania nanoparticles is much more homogenous with the presence of Hypermer KD77.

Viscosity control

When 50 wt% of barium carbonate nanoparticles were dispersed in water, the viscosity was dramatically reduced with the presence of Hypermer KD77. Uniform distribution of a nanomaterials with our nanodispersants and emulsifiers makes a wide variety of nanoparticle formulations viable.
