VANCOUVER, British Columbia, Sept. 16, 2025 (GLOBE NEWSWIRE) -- HydroGraph Clean Power Inc. (CSE: HG) (OTCQB: HGRAF) ("HydroGraph"), a leading producer of ultra-pure graphene, today announced that a new peer-reviewed study shows that aerogel ink made with HydroGraph graphene can increase the heat transfer coefficient (HTC) of copper by 152%. The study's results demonstrate the viability of using graphene for high-performance, scalable thermal management coatings in microelectronics.
The study, published in Graphene and 2D Materials (Springer), confirmed that HydroGraph's oxygenated graphene ink coatings dramatically enhanced cooling for high-powered microelectronics, such as those used in computers, electric vehicles, data centers, aerospace, and other solid-state applications. Using a scalable aerosol process, graphene coatings achieved over one and a half times the heat transfer of bare copper and a 40% increase in CHF (critical heat flux). The breakthrough not only represents superior heat conductivity but also an engineered surface texture that accelerates cooling due to bubble formation and evaporation.
From a commercial standpoint, the lab research illustrates the potential of using graphene aerogel ink as a cost-effective solution for microelectronics heat management. According to Verified Market Reports, the market for thermal management materials in microelectronics was valued at $7.21 billion in 2024 and is projected to reach $12.6 billion by 2033.
"The study highlights the potential of graphene in developing new compounds for next-generation electronics cooling," said Ranjith Divigalpitiya, Chief Science Officer for HydroGraph. "This research shows that the surface texture and bubble behavior of graphene aerosol coatings are more effective at heat dissipation than raw thermal materials. By pushing the boundaries of conventional conductivity cooling, HydroGraph is positioned to deliver new scalable and sustainable heat management solutions that improve the efficiency and extend the useful life of electronic devices."
