A new nanomaterial that improves plastics could result in more fuel-efficient airplanes and cars.

The material, developed by a Michigan State University (MSU) researcher and his students, is called xGnP Exfoliated Graphite NanoPlatelets. It involves the addition of nanomaterial, materials as small as one-tenth of a micrometer, to make plastic stiffer, lighter and stronger. Lighter components could mean lesser fuel consumption in the propulsion for typically heavy vehicles.

Lawrence Drzal, University Distinguished Professor of chemical engineering and materials science at MSU and director of the university’s Composite Materials and Structure Center, led the research group that developed the product, which is considered to be a practical, inexpensive material that has a unique set of physical, chemical and morphological attributes. The nanoscale material, which is electrically and thermally conductive, has reduced flammability and barrier properties, he said.

The grapheme nanoparticles are being manufactured by a new startup company XG Scienes Inc. Located in Michigan, it is a spin-off of intellectual property owned by MSU. XG Sciences has an exclusive license to manufacture this material.

The material is said to be a good electrical conductor and can be used for lithium-ion batteries as well as capable of being used to make transparent conductive coatings for solar cells.

Aside from its potential use in the aerospace and automotive sectors, it also has potential to be used in developing more durable medical and sports equipment as well as packaging.
