"With the graphene, the mosquitoes were not even landing on the skin patch – said Brown Ph.D student Cintia Castillho, who is the study's lead author. "We had assumed that there would be a physical barrier to biting, through puncture resistance, but when we saw these experiments we started to think that it was a chemical barrier that prevents mosquitoes from sensing that someone is there." In the study, researchers covered the graphene oxide film covered by cheesecloth or just cheesecloth. Those who were covered in graphene did not receive a single bite.
Unfortunately, graphene oxide becomes less effective when wet, which is exactly the type of environment where mosquitoes thrive. Scientists found that mosquitoes were able to puncture through graphene oxide films that were soaked in water.
One drawback is that RGO is not breathable, so it's unlikely to be used in camping clothing , Scientists hope to find a way to stabilize graphene so it remains strong when wet. Brown University professor Robert Hurt.
If you're curious about graphene, you will not have long to wait. Makers of outdoor gear and electronics are already adding graphene to jackets, battery packs, shoes and more.
