Using the photopyroelectric method, we have determined the thermal resistance r and the thermal conductivity k of adhesive tapes, which are consistent with those previously reported for similar samples. Moreover, the method is capable of separating the different components of r that add up in the total resistance introduced by an adhesive tape placed between two surfaces: A component due to the sample material itself, a component in the presence of material inhomogeneities, and a contact resistance due to surface roughness. The first two components are characteristic of the sample material while the latter depends on the adhesive properties of the sample and on the surface state of the support material. In our case, it was equivalent to an air gap in the submicron range. (C) 2003 American Institute of Physics.
