Webinar Overview

This one-hour webinar will investigate the advantages and use of atomic force microscopes (AFMs) when studying mechanics of soft materials. We will describe AFM methods to obtain absolute values of elastic modulus. We will demonstrate using polystyrene and polyurethane polymers that the bulk moduli of elasticity (the Young’s modulus) can be measured starting from indentations of as small as 2-3 nm. This can be done when using either Force Volume or PeakForce QNM modes, allowing access to mechanical property mapping over a wide range of deformation timescales.
Recent developments now allow different deformation models to be applied and the off-line examination of individual force curves from anywhere in the image for an even better understanding of the details of the tip-sample interaction.

The live broadcast will include a fully interactive Q&A session to answer all of your applications questions. Register today to reserve your seat.
