Perpetuus reports positive outcomes of GNPs-enhanced cooling fluid test

In a series of controlled laboratory experiments, the addition of 0.1% SE-GNPs (functionalized with oxygen groups) to a 25% propylene glycol, 75% water solution produced a consistent temperature reduction of approximately 6°C compared with the base fluid alone. The results were repeatable across multiple test runs. The experiments were conducted in a static test configuration designed to isolate material behavior and confirm result consistency. Further validation under forced flow conditions and application specific cooling geometries is currently underway.

UK-based Perpetuus Advanced Materials has reported a reduction in operating temperature using low loadings of plasma treated, surface engineered graphene nanoplatelets (SE-GNPs) homogeneously dispersed into a standard propylene glycol water cooling fluid.In a series of controlled laboratory experiments, the addition of 0.1% SE-GNPs (functionalized with oxygen groups) to a 25% propylene glycol, 75% water solution produced a consistent temperature reduction of approximately 6°C compared with the base fluid alone.
