  • Patent number: 10435605
    Abstract: A surfactant suitable for use as an additive in the heat transfer liquid of a heating and/or cooling system, wherein the surfactant comprises a coconut-derived surfactant, the preferred coconut-derived surfactant being a non-ionic, coco-glucoside. The surfactant can be used as an additive in a heat transfer fluid of a wet central heating system or a chiller circuit at a concentration of between 800 ppm and 1500 ppm, but preferably 1200 ppm, as this has surprisingly been found to yield an optimum reduction in the surface tension of the heat transfer fluid, whilst not significantly or appreciably increasing the specific heat capacity of the heat transfer fluid.

  • Publication number: 20140299811
    Abstract: Disclosed are methods for forming carbon-based fillers as may be utilized in forming highly thermal conductive nanocomposite materials. Formation methods include treatment of an expanded graphite with an alcohol/water mixture followed by further exfoliation of the graphite to form extremely thin carbon nanosheets that are on the order of between about 2 and about 10 nanometers in thickness. Disclosed carbon nanosheets can be functionalized and/or can be incorporated in nanocomposites with extremely high thermal conductivities. Disclosed methods and materials can prove highly valuable in many technological applications including, for instance, in formation of heat management materials for protective clothing and as may be useful in space exploration or in others that require efficient yet light-weight and flexible thermal management solutions.
