==Types of interaction between fillers and matrix==

The mechanical properties of filled [[Elastomers|elastomers]] are decisively influenced by the dispersion of the fillers (carbon black, silica, etc.), which must therefore be analyzed in detail [1]. The filler distribution in elastomer materials is influenced by thermodynamic interactions in the form of

– Polymer–filler interactions

– filler–filler interactions (filler interactions)

as well as the mixing conditions during production [2].

During mixing, larger agglomerates are broken down into smaller aggregates and distributed in the matrix [3, 4]. The quality of a mixture depends on thermodynamic aspects, i.e. essentially on the complex interactions in the discrete polymer (rubber) phase, given comparable particle sizes of the fillers and additives (anti-ageing agents, processing aids, etc.) and structure. A good filler–filler interaction favours the re-agglomeration of the particles, thus reducing the rubber–filler interface and leading to the formation of filler networks [4].

==Description of micro- and macrodispersion in elastomers==

Depending on the particle size, the dispersion state can be characterized using very different methods [4], whereby a distinction is generally made between microdispersion (polymer–filler interaction) and macrodispersion (filler–filler interactions) [5]:

* Assessment of microdispersion
:– Small-angle X-ray scattering (SAXS)
:– [[Transmission Electron Microscopy|Transmission electron microscopy]] (TEM)
:– [[Atomic Force Microscopy|Atomic force microscopy (AFM)]]
* Assessment of macrodispersion
:– Gloss section method ([[Macrodispersion Degree Elastomers|degree of macrodispersion]])
:– Electrical conductivity measurement ([[Volume Resistance|volume resistance]])
:– Black incorporation time (BIT)
