„Photothermal techniques: versatile multipurpose methodologies for the study of composite materials“


Photothermal techniques are based on the generation of trains of thermal waves in a material, induced by its illumination with an adequate light source. Due to its intrinsic nature, thermal waves involve a myriad of intertwined physical process related to transport phenomena, mechanical vibration, phase transitions and chemical reactions, among others. Their behavior is strongly influenced by the geometry, the presence of interfaces, and by the micro and nanostructure. The way in which the thermal wave phenomena are induced as well as the way of detecting them define the type of phenomena and the spatial and temporal resolution which can be achieved. Those characteristics make photothermal techniques very well suited for the study of a wide variety of composite materials. In this talk, we present results for the measurement of physical properties of layered, composite, granular and smart materials using different photothermal techniques. Results using photoacoustics, thermal wave cavity, photothermal radiometry, thermography, flash radiometry and transient grating are presented. It is shown that the technique can provide reliable results in a wide range of densities, thermal properties as well as in the study of time dependent phenomena.
