Abstract: This article investigates how the thermal conductivity of a resorcinol-formaldehyde aerogels varies with increasing resorcinol (R) to water (W) ratios. The thermal conductivity was measured using the Hot disk transient plane source (TPS) method with a TPS 2500 S. As the R:W increases so does the thermal conductivity, this is because there is more conductive solids present to transfer more energy.
