Three-dimensional fillers

Mesoporous silica with honeycomb-hke porous structure has attracted a great deal of attention due to its high specific surface area, large pore volume, timable pore size with a ncff-row distribution (2-50 nm), good chemiccd cuid thermal stability, non-toxic nature, easily modified surface properties, good biocompatibility, low mriss density cuid compositions

Even dynamic measurements have been made on mixtures of carbon black with decane and liquid paraffin [22], carbon black suspensions in ethylene vinylacetate copolymers [23], or on clay/water systems [24,25]. The corresponding results show that the storage modulus decreases with dynamic amplitude in a manner similar to that of conventional rubber (e.g., NR/carbon blacks). This demonstrates the existence and properties of physical carbon black structures in the absence of rubber. Further, these results indicate that structure effects of the filler determine the Payne-effect primarily. The elastomer seems to act merely as a dispersing medium that influences the magnitude of agglomeration and distribution of filler, but does not have visible influence on the overall characteristics of three-dimensional filler networks or filler clusters, respectively. The elastomer matrix allows the filler structure to reform after breakdown with increasing strain amplitude.

The filler-filler network can be reformed again after a certain time interval. Payne revealed that the value of E is largely recoverable upon return to smaller amplitudes in the linear regime. So, flexible mbber chains allow the filler particles to rearrange again to form a three-dimensional filler network in the rubber matrix [99]. In order to investigate the ability to recover the strain sweep experiments were also carried out in the reverse direction from higher to lower strain amplitudes for the samples with unmodified CNT dispersed by ethanoUc suspension.
