Graphene continues to emerge as one of the world’s most innovative materials of the future following test work by Sparc Technologies (ASX: SPN) confirming its significant performance as a protective layer that can prevent corrosion.
The testing, which was performed with the University of Adelaide, saw graphene-based additives applied to various steel panels. Over 10 weeks, the panels were subjected to a range of hot UV lighting, salt sprays and freezing – conditions that would mimic the natural world.
At the conclusion of the test, improvement in adhesion increased up to 19% in single coat systems while triple coat systems saw improvement of up to 73%.
“The results from this round of test work are extremely encouraging. Test work has been undertaken to conform to ISO standards which enables us to target our vast industrial customer base to assess the results objectively,” said Sparc Managing Director, Tom Spurling.
“Sparc will now use the data derived from this test work, build on it, and continue to refine the optimal graphene formulation for the coatings additive so as to maximise performance.”
In commercial context, the test results highlight how low graphene additive levels have the potential to significantly reduce maintenance costs of steel-based structures and machinery while optimising cost efficiencies through manufacturing.
Anti-corrosion additive is just one use for graphene flagged by Sparc, which specialises in the extraction and application of graphene whilst also exploring environmental remediation and bio-medical applications.
Last month, Sparc launched their bio-medical sensor project in collaboration with the University of Adelaide. The project is aiming to develop graphene-based sensing devices that can be used remotely for the early detection and management of disease.
SPN shares responded well to Sparc’s anti-corrosion testing to reach a high of $0.355 in the first 20 minutes of trade, a rise of 14.5% on their previous $0.31 close.
