Time-of-Γight secondary ion mass spectrometry (ToF-SIMS) and atomic force microscopy (AFM) were utilized to characterize polypropylenes of di β erent stereoregularity (atactic, syndiotactic and isotactic) deposited on gold-or silver-coated mica surfaces. The AFM images clearly revealed distinctive su
