Graphene enhanced plastics

Comparison of xGnP (graphene additive) to other nanocomposite additives.

Michigan state University is using the recent discovery that graphene is the strongest material ever and using graphene additives to make stiffer, stronger and lighter plastics.

The material – xGnP Exfoliated Graphite NanoPlatelets - can an either be used as an additive to plastics or by itself it can make a transformational change in the performance of many advanced electronic and energy devices,” Drzal said. “It can do so because it’s a nanoparticle with a unique shape made from environmentally benign carbon, and it can be made at a very reasonable cost.”

Background

Boron nitride is a synthetic material, which although discovered in the early 19^th century was not developed as a commercial material until the latter half of the 20^th century. Boron and nitrogen are neighbours of carbon in the periodic table - in combination boron and nitrogen have the same number of outer shell electrons - the atomic radii of boron and nitrogen are similar to that of carbon. It is not surprising therefore that boron nitride and carbon exhibit similarity in their crystal structure.

In the same way that carbon exists as graphite and diamond, boron nitride can be synthesised in hexagonal and cubic forms.
