Abstract:
Carbon nanotubes and graphene possess extraordinary properties: higher thermal
conductivity than any bulk material, mechanical strength 10-to-100 times greater
than steel on a mass basis, and electrical current capacity 1000 times greater than
copper. These materials have wide-reaching energy and sustainability applications
to thermal energy storage, electrical energy storage, high thermal conductivity
composites, high strength composites, and water purification. For example, just
one volume percent of graphene additives can almost double the thermal
conductivity of alkane-based thermal energy storage materials, nearly doubling
the thermal energy storage rate. This presentation will explore how carbon
nanotubes and graphene impact thermal conductivity when added in small
volume fractions to gas, liquids and solids through the study of carbon nanotube
aerogels (ultra lightweight, 8 kg/m3, 99.6% void space), and phase change
nanocomposites (hexadecane-graphene).
