Khranovskyy is one of the founders behind Grafren, a company of 4 employees with over 15 years of experience in materials science and expertise in nanomaterials. Graphene in its foundation is a material that came into existence in 2011, which in the same year became a Nobel Prize winner for the invention. 10 years later, Grafren was founded in Linköping, and has patented technologies that allow graphene to be used on all sorts of products. By applying graphene, which at the atomic level is integrated into a layer like a DNA spiral pattern, it is possible to create a reinforcing and safer material that can be used for everything from drones that need to be able to un-freeze their wings to nursing mothers who need a bra that maintains a uniform temperature. With collaborations and pilot projects with giants such as SAAB and RISE to drone manufacturers, there are endless possibilities for Grafren.
The year was 2018, and two scientists wanted to create something that would remain after their observance, that would affect the world for real. To see it for generations to come and become a part of the history books. “I started thinking at the age of 40, what am I doing in the world and how can I contribute? I have been researching for a lot of years, with over 80 research papers and recognitions. But now I felt that I wanted to create something that will continue to exist, for real.” In 2004, Khranovskyy came to Sweden, but he has also spent time in both Norway and Portugal, working as a researcher in materials science.
At Grafren, which runs a small scale production, a lot can still be done. Companies engaged in the same business do not have the expertise and patents of Grafren, and moreover cannot achieve the scale and cost-effectiveness of their production in the same way, something that Khranovskyy is extremely proud of.
Graphene is the thinnest and strongest material in the world, which is also electrically conductive. It is only one atom layer thin, so it is not possible to make it thinner. What Grafren does is integrate graphene with other materials as a coating on a nanoscale - textiles and composites, for example, and then the resulting material gains additional properties and new abilities. Graphene is thus, like thunder honey, which, by applying to another material, acquires magical properties.
