Abstract

The micro Thermal Analysis μTA is a new technology combining the high resolution positioning techniques of the scanning probe microscopy with the quantitative analysis techniques of the conventional thermal analysis. In the first mode of the operation contrasts in the thermal properties can be acquired parallel to topography imaging. In the second mode of the operation selected positions of interest within the images can then be chosen for a further thermal analysis. Thus glass transition temperatures (Tg) or melting temperatures can be measured with a spatial resolution of few μm. In this article the new technique and capabilities of the μTA are explored and demonstrated by interphase characterization of adhesive bonded joints and fibre composites.
