PS-LDPE-GS

 A two-component polymer sample mounted on a glass slide.  This sample provides excellent contrast in elastic modulus, adhesion, and dissipation contrast.  A blend of Polystyrene spin-cast onto a silicon substrate, creating a film with varying material properties.  The PS regions of the sample have elastic modulus numbers around 2GPa, while the other regions have elastic modulus numbers around 0.1GPa.

· NOTE:  The modulus of this sample and its variation over time are only approximately known.
