TL;DR: In this article, the addition of TiO2 appeared to decrease the tensile properties of poly(methyl methacrylate)(PMMA) and acrylic rubber (AR), but increased the impact strength of PMMA.
Abstract: Polymer blends of poly(methyl methacrylate)(PMMA) and acrylic rubber(AR) were manufactured with the addition of titanium dioxide (TiO2). TiO2 was initially added to the AR phase in AR/PMMA blends. The impact strength of PMMA improved with AR loading. The addition of TiO2 appeared to decrease the tensile properties of the blends with AR of 10-30 wt% of AR, but increased with AR of 40-50 wt%, this being related to distribution level of TiO2. UV radiation deteriorated the overall mechanical properties, where TiO2 could retain the properties. To achieve acceptable antibacterial performance, AR loadings of 40 and 50 wt% in AR-TiO2/PMMA blends are recommended, together with TiO2 loadings of 1.5 pph and 0.5 pph, respectively.

TL;DR: In this article, the influence of the addition of tire rubber in concrete was evaluated, to partially replace the fine aggregate of sand particles, and the rubber fibers were also surface treated with different solvents to improve adhesion of the fibers to the concrete matrix.
Abstract: In this study, the influence of the addition of tire rubber in concrete was evaluated, to partially replace the fine aggregate of sand particles. The rubber fibers were also surface treated with different solvents to improve adhesion of the fibers to the concrete matrix. Compressive strength, slump test, Fourier Transform Infrared Spectroscopy of concrete samples were performed at time intervals of up to 28 days. The results showed a decrease on mechanical property values after the addition of tire rubber without treatment as well as a decrease of workability. It was also observed that the tire rubber treatment with acetone caused an increase of the mechanical strength of the samples.

TL;DR: In this article, the effect of different loadings of titanium dioxide particles on the chemical structure, morphology, mechanical and thermo-mechanical properties of the natural rubber-based composites was investigated.
Abstract: The aim of this work was to prepare and characterize the natural rubber vulcanizates containing different amounts of titanium dioxide particles. At first, a rubber mixture was prepared using a laboratory two-roll mill and then samples were vulcanized by a hydraulic press. The formulation of the rubber mixture and rubber-processing technique were based on our earlier investigations. Samples were obtained with different titanium dioxide loadings of 15, 25, 45, and 85 parts by weight per hundred parts of natural rubber. This research is focused on the determination of the influence of different loadings of titanium oxide particles on the chemical structure, morphology, mechanical and thermo-mechanical properties of the natural rubber-based composites. It was found that vulcanizates with different amounts of TiO2 particles possess good characteristic in terms of all measured properties. The results of Fourier transform infrared spectroscopy analysis showed that the chemical structure of the obtained natural-based composites was not influenced by titanium dioxide particles. The SEM micrographs showed the uniform dispersion of TiO2 particles in the natural rubber matrix. The agglomeration of filler was seen at the higher contents of TiO2 in the matrix. The thermogravimetric analysis showed slightly different thermal stability for the obtained natural rubber composites. The dynamic mechanical thermal analysis showed that the prepared materials have similar glass transition temperatures. However, increase in the content of titanium dioxide in the obtained materials is connected with higher energy loss (higher dissipation of energy) during the mechanical work of material and higher cross-link density of the prepared materials.

TL;DR: In-situ and ex-Situ methods were applied to modify silica particles in order to investigate their effects on the reinforcement of silicone rubber as discussed by the authors, and the results indicated that the in-suit modification was more beneficial to preparing silica particle with irregular shape and higher BET surface area in comparison with ex-simultaneous modification.
