Filler-filler and filler-matrix interactions in polymer composites increase with filler concentration and strongly influence the mechanical and rheological properties of polymer composites. By means of the spouted bed spray granulation process polymer composites with an extremely high concentration of inorganic fillers can be prepared. In this work, the viscoelastic properties of highly filled composites of poly(vinyl butyral) (PVB) and alumina particles are studied in the glassy, entanglement and terminal flow regime of poly(vinyl butyral). Ceramic-polymer composites with a volume concentration of inorganic particles between 61 vol% and 77 vol% were prepared. Such large filler fractions imply a strong effect of filler-filler interactions on the viscoelastic properties of the composite. Dynamic-mechanical thermal analysis reveals that the composites are characterized by a predominantly elastic behaviour below and above the glass transition temperature of the polymer phase because of strongly pronounced filler-filler and polymer-filler interactions. A phenomenological equation is proposed in order to describe the reinforcement effect which implies an increase of storage modulus by a factor of up to four orders of magnitude. The results of frequency and strain sweeps in the oscillatory mode show that the polymer phase strongly influences the deformation of the contact network of inorganic particles. Differential scanning calorimetry and broadband dielectric spectroscopy indicate that the glass transition temperature of poly(vinyl butyral) does not significantly differ within experimental resolution for pristine PVB and the PVB phase in the composites.

“…Combination of CB + carbon nanotube, organoclay + nano‐silica, organoclay + carbon nanotube, CB + Graphene, organoclay + nano‐CaCO 3 , and short jute fibers+ carbon nanotube was also the subject of some studies in rubber–hybrid filler nanocomposites. The synchronous use of CB and nanoclay has been reported.…”

Rubber nanocomposites containing one type of nanofiller are common and are widely established in the research field. In this study, nitrile rubber (NBR) based ternary nanocomposites containing modified silicate (Cloisite 30B) and also nano-calcium carbonate (nano-CaCO 3 ) were prepared using a laboratory internal mixer (simple melt mixing). Effects of the hybrid filler system (filler phase have two kind of fillers) on the cure rheometry, morphology, swelling, and mechanical and dynamic-mechanical properties of the NBR were investigated. Concentration of nano-CaCO 3 [0, 5, 10, and 15 parts per one hundred parts of rubber by weight (phr)] and organoclay (0, 3, and 6 phr) in NBR was varied. The microstructure and homogeneity of the compounds were confirmed by studying the dispersion of nanoparticles in NBR via X-ray diffraction and field emission scanning electron microscopy. Based on the results of morphology and mechanical properties, the dual-filler phase nanocomposites (hybrid nanocomposite) have higher performance in comparison with single-filler phase nanocomposites.

“…CNT-based polymer nanocomposites are well known attractive materials [8] [9] [10] [11], and they have been already proposed and reported for thermal energy harvesting. In specific, they are of particular interest due to their low thermal conductivity, high electrical conductivity, ease of production, relatively low cost, flexibility and high specific properties.…”
