“…One reason for the differentiated properties presented by the nanoscale is the distinct surface/volume proportion or aspect ratio that is not linear for different dimensional scales [1,2]. In general, the choice of polymer as a matrix or continuous phase is preferable since most have appreciable thermal and mechanical properties, and the natural rubber is a desirable candidate owing to its distinctive ability to incorporate large amounts, up to 600 phr, of solid and inert particles, maintaining acceptable mechanical properties [3,4].…”

Several composites and nanocomposites based on a polymeric matrix and ceramic fillers are being pursued for use as multifunctional and innovative materials. Nevertheless, there is a series of challenges to be solved in this area such as the understanding of the role of interfaces and the synergy between matrix and fillers. In this work, vulcanized natural rubber nanocomposites were prepared with different concentrations of two kinds of ceramic nanoparticles, potassium strontium niobate (KSr 2 Nb 5 O 15 or KSN) and nickel-zinc ferrite (Ni 0.5 Zn 0.5 Fe 2 O 4 or NZF), synthesized by a chemical method known as the modified polyol method. Morphological and thermal characterizations were carried out by AFM, TG/DTG, TG/FTIR and DSC. The thermal properties of nanocomposites were compared and discussed as functions of concentration, type and surface of nanoparticles. The results obtained suggest that the base concentration for both types of nanoparticles inside the polymer matrix volume greatly adds to the increase in thermal stability up to 11 % and the glass transition temperature up to 10°C. A similar evolution for the glass transition temperature (T g), thermal stability temperature (T S) and dielectric permittivity (e 0) was identified, suggesting that these phenomena are mainly dominated by the same mechanisms. These results point to the possibility for the thermal parameter modulation in magnetic and ferroelectric nanocomposites by means of a suitable control of concentration and properties of the KSN and NZF nanoparticles.

The carbon black, used in rubber compound as reinforcing filler, improves the strength, durability, and wear resistance of the rubber compound. However, it causes filler-filler interaction and results in extensive hysteresis energy losses on deformation. This research aims to reduce hysteresis energy loss of rubber compound by reducing filler-filler interaction and by improving the filler dispersion in rubber matrix. In this study, the effect of carbon black treated with benzyl tri-ethyl ammonium chloride (BTEAC) on solution styrene butadiene rubber and butadiene rubber (SSBR-BR) system was studied. Microscopic study of dispersion and distribution of carbon black in rubber matrix was performed and a significant improvement in dispersion of BTEAC treated carbon black in SSBR-BR rubber matrix was observed. As a result of increased interaction of BTEAC treated carbon black with rubber, the filler - filler interaction was significantly reduced, resulting lower hysteresis energy loss of the compound as expressed by loss tangent (tanδ) value and it has been observed that an extent of around 15% reduction in tanδ value was achieved in rubber compound consisting of BTEAC treated carbon black. In this research, the carbon black was treated with different concentration of BTEAC, such as 0.5%, 1% and 1.5% and the best balance of rubber properties was observed for 1% and 1.5% BTEAC treated carbon black.

“…Table 1 discloses the compounding ingredients used in this work. A blend of 60/40 NR/BR was selected to offer an optimum crack growth resistance, as previously reported [20,21]. While the total amount of hybrid filler was kept constant at 50 phr, the weight ratios of CB to SiO 2 were varied as follows: 50/0, 40/10, 30/20, 20/30, 10/40 and 0/50 and designated as CB/SiO 2 50/0, CB/SiO 2 40/10, CB/SiO 2 30/20, CB/SiO 2 20/30, CB/SiO 2 10/40 and CB/ SiO 2 0/50, respectively.…”

Influence of carbon black (CB)/precipitated silica (SiO2) hybrid ratio on properties of a passenger car tire (PCT) sidewall based on natural rubber (NR) and butadiene rubber (BR) blend was investigated. Rubbers filled with various hybrid filler ratios at a constant loading of 50 phr were prepared and tested. The filler reinforcement efficiency in association with crucial properties of the tire sidewall were of interest. Results show the enhanced rubber–filler interaction with increasing SiO2 fraction leading to the improvement in many vulcanizate properties including hardness, tensile strength, tear strength and fatigue resistance, at the expense of cure efficiency and hysteretic behaviors (i.e., reduced heat build-up resistance and increased dynamic set). The results also suggest the improvement in tire sidewall performance of the NR/BR vulcanizates reinforced with CB/SiO2 hybrid filler, compared to that of the CB-filled vulcanizate.
