Abstract: The thermal conductivity of nanoporous glass alumina films (NGAFs) were theoretically and experimentally studied in this paper. The thermal conductivity of pristine NGAFs and silver nanowire-infused NGAFs of various pore sizes and porosities were measured with a hot disk thermal constants analyser TPS 2500 S based on the transient plane source (TPS) method. Theoretical and experimental results were consistent with one another, and indicated that the pore radius and porosity of the films influenced thermal conductivity. Additionally, the Ag nanowires that were added to the NGAF matrix had no impact on thermal conductivity.
