Carbon blacks are used universally as fillers in polymer matrix for mechanical, electronical and thermal properties improvement. Plenty of studies show that the structure and surface properties affect the function of carbon blacks in polymer matrix intensively. However, the reinforcing mechanism is still controversial. In this study, we studied the structure of three carbon blacks by Dibutyl phthalate (DBP) absorption and atomic force microscopy (AFM) and analyzed the absorption/desorption forces of the three carbon blacks surface by force-distance curves. The results show that the carbon black with relatively high structure possesses more branches and bigger aggregation morphologies and shows the highest surface absorption/desorption forces, which may increase the reaction between carbon black and polymer matrix.

Abstract A series of rubber compounds filled with carbon blacks and silica has been studied by atomic force microscopy (AFM). The microdispersion of carbon black aggregates in rubber compounds can be clearly observed. The surface morphology of worn treads after road testing studied by AFM is also reported.

By using a solvent-based method composites of ethylenevinyl acetate copolymer and carbon black (EVA–CB) were synthesized for sensing BTEX (benzene, toluene, ethylbenzene and xylene) vapours. The composites were characterized using atomic force microscopy (AFM) in an electroconductive mode. Gas sensing results show that EVA-CB can reproducibly detect BTEX and that the response increases linearly with vapour concentration. Compared to gas-sensing measurements of gasoline vapours, the responses with toluene and ethylbenzene are different and can be explained by varying side chains of the benzene ring.
