“Isostructural Softening of the Filler Network in SBR/Silica Nanocomposites”
Abstract:
A new formulation of the widely used nanocomposites based on SBR and fractal silica fillers is proposed by substituting the usual covering and coupling agents with short chains (4 kg.mol-1) of polypropylene glycol (PPG) oligomers. We study in a systematic way the structural evolution as well as the changes in linear and non-linear mechanical properties of two series of samples varying: (i) the silica volume fraction in PPG-free samples, and (ii) the amount of PPG for a given silica content of 15 vol.%.
