High internal phase emulsions (HIPE) are materials with incredible microscale morphologies. They normally exhibit a pore like structure with polymerized scaffolding surrounding spherical voids. This portion of the sample was somewhat different however, it illustrates how the structure changes under deformation and how the polymer reacts to non-reversible strain. This image was taken using a scanning electron microscope (SEM) with a sample sputter coated in a fine layer of gold. Gold makes the sample conductive so that it may scatter incoming electrons from a concentrated electron beam to a detector thus creating an image.
