dc.description.abstract Polystyren/MWCNT komposity s obsahem MWCNT do 1 hm. % byly připraveny ve formě mikrokuliček suspenzní polymerizační technikou. Frakce 32-64 ?m byla zkoumána prostřednictvím SEM a TEM mikroskopie. Na povrchu kuliček není zaznamenám výskyt MWCNT. Řezy kuličkami ukazují na složení základních kuliček ze slinutých menších kuliček rozměrů v mikrometrech vytvářející heterogenní mezifázi. MWCNT nebyl zaznamenám uvnitř malých kuliček a zdá se že vyplňuje heterogenní fázi. Suspenze PS/MWCNT kuliček v silikonovém oleji vykazují elektrorheologický efect jehož intenzita silně závisí na obsahu MWCNT. cs
dc.description.abstract Polystyrene and polystyrene/multi-wall carbon nanotube composites, PS/MWNT, with MWNT content up to 1 wt.% were prepared in the form of microspheres through in situ suspension polymerization. The morphology of the fraction of 32-64 mu m was examined by SEM and TEM microscopy. On the surface of the spheres the presence of MWNT was not observed. The microspheres Intersections showed the structure of aggregates of sintered beads a few micrometers in size with heterogeneous interface. No MWNT material was observed inside the beads; it seemed to be situated in the heterogeneous phase of microspheres. Suspensions of PS/MWNT in silicone oil show electrorheological effect, whose intensity strongly depends on MWNT content in composite microspheres. en
