| Résumé : |
Transition temperature microscopy (TTM) is a novel local thermal analysis technique that maps spatial variations in thermal properties on length scales from millimeters to nanometers. Traditional bulk thermal analysis provides a sample averaged result and cannot generally supply sufficient information about complex structures or heterogeneities within films or coatings. There currently exists a nanoscale thermal analysis (nano-TA) technique in which a nanoscale thermal probe heats a localized region on the sample surface to measure its thermal properties, including thermal transition temperatures like crystalline melting points and glass transitions. TTM enables these nano-TA measurements to be carried out rapidly at a succession of points, thus creating automated high-resolution spatial maps of the thermal properties of a sample. In this article we also demonstrate how TTM can be used to characterize chemical and structural heterogeneities and thereby generate vital information in applications ranging from coating defects, to in-situ property measurement of individual layers in multilayered films, to the detection of gradients and interfaces. |
