Surface characterization of C-60-containing poly(ethyl methacrylate)/poly(ethyl methacrylate) blends
The surface properties Of C-60-containing poly(ethyl methaerylate)s (PEMA-C-60) and their blends with poly(ethyl methaerylate) (PEMA) were investigated by attenuated total reflectance Fourier transform infrared spectroscopy, scanning electron microscopy, time-of-flight secondary ion mass spectrometry, and contact-angle measurements. The polymer surface becomes more hydrophobic with increasing C-60 content in the polymer. The PEMA-C-60/PEMA blends show the surface enrichment of PEMA-C-60. There is a good correlation between the surface hydrophobicity and the surface enrichment of PEMA-C-60.
