Graphene as a sustainable building material? Combining jute and graphene as a new composite material could a create strong and sustainable building material.

“Scientists have combined graphene and jute to form a new composite material that is strong, durable and cheap to make. Researchers think the fiber-based composite material could be used to build cars, ships, wind turbine blades and even low-cost housing.
 
Jute are fibres sourced from the bark of the white jute, Corchorus capsularis, a shrub species cultivated in South America and Asia. The fibre is eco-friendly, as it is biodegradable and easily recycled.
 
Because it is relatively cheap and readily available — the second most abundant natural fibre after cotton — jute is ideal for use in commercial manufacturing.
 
Other natural fibre composites aren’t particularly strong, but lab tests proved the addition of graphene significantly improves jute’s material qualities.
 
“This is an example of judicious combination of low-value, carbon-neutral commodity fibers with an extremely small volume fraction of high-value graphene in order to create a material system that could replace energy-intensive carbon and glass fibers in a number of light-weight structural applications,” Prasad Potluri, researcher at the University of Manchester, said in a news release.
 
Researchers at Manchester’s National Graphene Institute created the new composite material by coating jute with graphene oxide and graphene flakes. The small additive resulted in a 200 percent increase in the material’s shear strength and a 100 percent increase in its bend strength.
 
Scientists detailed their new material in the journal Applied Materials and Interfaces.
