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.

Abstract The changes of the filler morphology of SBR vulcanizates loaded with 10 phr carbon black (N234 and N990) subjected to large strains were studied by Atomic Force Microscopy and image analysis. It was found that the filler particles tend to align in the force field. The average distance of the filler particles at the surface in the direction parallel and perpendicular to the strain direction is much smaller then according to affine deformation. The measurements give evidence of the inhomogeneous deformation of the rubber matrix and demonstrate the onset of failure at large deformation.

A New Technique

Abstract A new technique is proposed for analysis of the microstructure of carbon-black-filled rubbers using atomic force microscopy (AFM) images for data processing. The idea consists of segmenting the continuous relief of an AFM scan into isolated fragments that reflect the filler network in rubber. Two structural states of filler are defined: aggregates (small-sized, branched fragments of the relief) and micropellets (dense, round-shape structures). All the information regarding the geometry and coordinates of fragments is stored in computer memory. Based on observations of the relative position of the fragments within a relief, separate aggregates are assembled into secondary structures—agglomerates. The microstructure of five polymers (SBR or IR) filled with N220 carbon black (10, 30, and 50 phr) was investigated. Two materials were loaded in tensile tests to examine the microstructure of extended samples. A comparative analysis of the following microstructure parameters is presented: character of distribution and dispersion of filler in the matrix, fractal characteristics of aggregates and agglomerates, aggregate size distribution, micropellets mass fraction and sizes, and the variation of orientation of the filler, its sizes, and the distance between the neighboring pairs of aggregates in materials subjected to tension.

High Structure

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.
