Crosslinked immiscible elastomer blends BR/IR, SBR/IR and SBR/BR were
examined Atomic-Force-Microscopy (AFM). The typical features of the ph
ase morphology are imaged more reliably by the difference of the frict
ion coefficient (AFM lateral mode) than by the difference of the heigh
t profile (AFM height mode). light optical microscopy as reference met
hode shows similar results.
