Researchers assess health hazards of graphene-enhanced composites

An international research team of the Graphene Flagship project, led by Empa, has conducted a study on the health risks of graphene-containing nanoparticles and found that graphene-based particles released from polymer composites after abrasion induce negligible health effects.

Graphene-related materials (GRMs) are often used to reinforce polymers. In small concentrations of up to five weight percent, GRMs can significantly enhance the strength, electrical conductivity and thermal transport of composites for a variety of applications. However, being a relatively new set of materials, graphene and GRMs need to be carefully assessed in order to identify potential adverse effects prior commercialization.
