Measuring nanoscale viscoelastic properties with AFM-based nanoscale DMA

The development of heterogeneous materials like polymer composites, blends, and multilayers is of considerable importance in the chemicals industry. Bulk viscoelastic measurements are routine in establishing structure-property relationships for these materials. In this application note from Bruker, explore how the development of the AFM-nDMA™ mode, can avoid issues associated with measuring nanoscale viscoelastic properties and how the frequency and temperature dependence of viscoelastic properties in rheologically relevant ranges can be directly measured with 10 nm spatial resolution.
