Riassunto
SBR nanocomposites based on two different types of fillers, Sepiolite and POSS-silica, were analysed using 1H Time-Domain NMR techniques. The combination of solid echo and CPMG experiments, together with a suitable strategy of data analysis, allowed a complete characterization of the dynamically distinguishable regions of the nanocomposites and, in particular, a quantitative evaluation of the bound rubber content.
Moreover, a similar 1H relaxometric approach was applied to the study limonene-encapsulating Trehalose systems, in order to investigate the physico-chemical properties of the trehalose matrices
