Improved dispersion and mechanical properties of hybrid nanocomposites

Formation of functionalized nanoclusters by solvent evaporation and their effect on the physicochemical properties of dental composite resins

“…Recently, nanoparticles have been used as reinforcing material due to better mechanical properties of composite materials obtained with them in comparison to bare polymer matrixes or polymers reinforced with microfillers [4,5], and the generation of translucent dental materials, which are not feasible with reinforcing particles sizing more than 200 nm. However, nanoparticles can only be used at a relatively low concentration (<10 wt%) in order to produce resins composites with manageable viscosities and in a non-aggregated state [6][7][8]. The final polymerized composite material, at this low nanoparticles concentration, shows low mechanical properties that are unacceptable for dental restorative materials.…”

Experimental study and optimization of damping properties of epoxy-based nanocomposite: Effect of using nanosilica and high-impact polystyrene by mixture design approach

“…If used two or more kind of nano or micro particle in matrix, the composite is named hybrid nano composite [21]. Rostamiyan et al [2,22,23] showed that using combination of HIPS as thermoplastic phase and nanomaterials as nano reinforcement improved mechanical properties such as tensile, flexural, compression and impact strength.…”

Hybrid Nanoparticle-Based XLPE/SiO2/TiO2 and XLPE/SiO2 Nanocomposites: Nanoscale Hybrid Assembling, Mechanics and Thermal properties

“…Very recently, hybrid system of two or more nanoparticles has found promising in enhancing the dispersion of nanoparticles and thus by increasing the mechanical and thermal properties [5,6]. Uddin and Sun have reported that silica nanoparticles reduced the agglomeration of alumina nanoparticles in the epoxy matrix dispersed by sonication method [7]. In the present study, it is tried to introduce the synergistic effect of SiO 2 and TiO 2 nanoparticles in effective dispersion in XLPE matrix by eliminating the tendency of aggregation by the combined effect of surface treatment on nanoparticles and the difference in surface characteristics of two kinds of nanoparticles.…”
