Atomic Force and Electron Scanning Microscopy of Silicone Composites
The conclusions of direct numerical simulation obtained earlier, within the cluster quantum-chemical approximation, are used in experimental investigations of polydimethylsiloxane composites with schungit or silica. The surface structure of these composites by atomic force and scanning electron microscopy was studied. Correlation of the distribution of micro- and nanodimensional fillers in the polymer matrix with the physical-mechanical properties of the composites was established.

Composition and Structure Influence on Properties of Elastomeric Composites with Silicon Dioxide Fillers
The problem of finding effective polymer elastomer fillers now is actual task. This chapter presents experimental studies of composites based on industrial synthetic butadiene-styrene rubber with amorphous silicon dioxide filler particles, obtained from rice husk ash processing products. The new methodology was developed for producing highly dispersed fillers powders with micro- and nano-sizes using a planetary ball mill. The synthesized composites surface structure was investigated using scanning electron and atomic force microscopy. The composites elastic-strength properties were studied by tensile testing machine. The significant influence of the surface functionality and the carbon/silicon dioxide ratio in fillers on the elastomeric composites mechanical properties is shown. It is concluded that these new classes of reinforcing fillers can be recommended for practical use.
