摘要

The non-covalent filler-matrix interactions in poly(methyl methacrylate) (PMMA) composites filled with carbon nanofiber (CNF) and oxidized carbon nanofiber (ox-CNF) were analyzed. Significantly improved state of filler dispersion was observed in composites containing ox-CNF. A direct evidence of hydrogen bonding between PMMA molecules and ox-CNF particles was obtained from the analysis of FT-IR spectra. Fluorescence emission spectroscopy did not reveal any insight on the filler-matrix interactions in composites, due to the lack of chromophores on PMMA and due to the presence of UV stabilizers.
