The technique of polymer blending has been used to create new types of polymers with desirable properties in the past decade. Force Modulation Microscopy (FMM) provides a local contrast due to the local elasticity difference of a sample surface in addition to topography information [1]. The mechanical properties are examined continuously over the extended area and force modulation mode is utilized to identify two phases to measure local elastic properties [2]. Poly(styrene-isobutylene-styrene) (SIBS) blended with poly(styrene-maleic anhydride) (SMA) was characterized by Atomic Force Microscopy (AFM) to understand phase identification. Young's moduli of bulk materials were obtained by tensile testing machine from the slope of stress-strain curve [3]. The localized elastic modulus of each phase is obtained by F-D curve through adopting the mathematical theory [4] and image analysis was employed to measure the volume fraction from FMM images at different blending ratios.
