“…According to Bragg's formula (Equation (1)), the three 2θ values reported in Figure 1 correspond at the following interlayer distances: 3.3, 1.8 and 1.2 nm, respectively. The first peak, corresponding at the (001) reflection, is representative of the regularly stacked layers; the high order reflections, corresponding to the (002) and (003) reflections, derive from the regular arrangement of the intercalant [37]. Considering PE/clay fibers, it can be seen that in every case the three sharp peaks of D67G disappeared, indicating the achievement of intercalated/exfoliated structure with interlayer higher than 4.4 nm (corresponding at 2θ value < 2 • ).…”

Abstract:In this work, the influence of composition and cold-drawing on nano-and micro-scale morphology and tensile mechanical properties of PE/organoclay nanocomposite fibers was investigated. Nanocomposites were prepared by melt compounding in a twin-screw extruder, using a maleic anhydride grafted linear low density polyethylene (LLDPE-g-MA) and an organomodified montmorillonite (Dellite 67G) at three different loadings (3, 5 and 10 wt %). Fibers were produced by a single-screw extruder and drawn at five draw ratios (DRs): 7.25, 10, 13.5, 16 and 19. All nanocomposites, characterized by XRD, SEM, TEM, and FT-IR techniques, showed an intercalated/exfoliated morphology. The study evidenced that the nanoclay presence significantly increases both elastic modulus (up to +115% for fibers containing 10 wt % of D67G) and drawability of as-spun nanocomposite fibers. Moreover, at fixed nanocomposite composition, the cold-drawing process increases fibers elastic modulus and tensile strength at increasing DRs. However, at high DRs, "face-to-edge" rearrangement phenomena of clay layers (i.e., clay layers tend to rotate and touch each other) arise in fibers at high nanoclay loadings. Finally, nanocomposite fibers show a lower diameter reduction during drawing, with respect to the plain system, and surface feature of adjustable roughness by controlling the composition and the drawing conditions.

“…Among the nanometer-scale reinforcing particles, layered silicates have attracted a tremendous interest due to the considerable property improvements that could result if an exfoliated structure is obtained with a full separation of the clay layers leading to a large interfacial contact area with the polymer [9].…”

Carbon nanostructures including carbon black, carbon nanotubes, graphite or graphene have attracted a tremendous interest as fillers for elastomeric compounds. The preparation methods of nanocomposites that have a strong impact on the state of filler dispersion and thus on the properties of the resulting composites, are briefly described. At a same filler loading, considerable improvement in stiffness is imparted to the host polymeric matrix by the carbon nanomaterials with regard to that provided by the conventional carbon black particles. It is mainly attributed to the high aspect ratio of the nanostructures rather than to strong polymer-filler interactions. The orienting capability of the anisotropic fillers under strain as well the formation of a filler network, have to be taken into account to explain the high level of reinforcements. A comparison of the efficiency of the different carbon nanostructures is carried out through their mechanical and electrical properties but no clear picture can be obtained since the composite properties are strongly affected by the state of filler dispersion.

“…Rubber nanocomposites have applications include a large number of latex and dry rubber goods. Some of them are sports goods, tubes, foams, packing membranes, catheters, tire inner tubes, automobile components, inner bladders of play balls, ball covers, sensing devices and related products, electrical devices, electrical shielding, and the applications where electrical heating is required [3].As a results of higher overall performance of nanocomposites, especially focused on fuel efficiency through reduced weight and energy absorption from rolling resistance, it is incorporate into tire components [15]. In this research sample were prepared from SBR matrix reinforced by different loading level of nano silica and then the mechanical properties was studied.…”

Abstract:The aim of this research is to study the effect of nano silica which use as a filler with loading level (0.1, 0.3, 0.5, 1, 3, 5, 10, 20, 30, 40 pphr) on mechanical properties of SBR such as Tensile strength, elastic modulus, hardness, abrasion, fatigue and tear resistance. The results show that on addition of small quantities of nano silica an increase of mechanical properties occurs. While at high percent of nano silica aggregation in rubber matrix occurs and decrease themechanical properties.
