“…But some carbon-based materials can be directly dispersed in polymers that are fluid at room temperature like low molecular weight poly(dimethylsiloxanes) before proceeding to the curing reaction [21]. A polymer latex instead of a polymer solution has been used for the synthesis of rubber-clay nanocomposites by co-coagulating the rubber latex and a clay aqueous suspension [22][23][24]. The composites prepared by the latex route have been shown to display a fine dispersed phase structure and good mechanical properties.…”

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.

“…The layered silicates dispersed at the nanosized level are reported to provide an effective reinforcement to synthetic and natural rubber materials [28][29][30][31]. There are very important studies on the preparation and properties of rubber/clay nanocomposites, especially by means of a conventional rubber compounding process.…”

“…There are very important studies on the preparation and properties of rubber/clay nanocomposites, especially by means of a conventional rubber compounding process. Wang et al [29] prepared three kinds of rubber/clay nanocomposites by latex and solution methods. They showed that clay could be dispersed in the rubber matrix as one or several layers, while polymer molecules intercalated to the clay galleries; compared with other methods, the latex method was more convenient and could be widely used to prepare polymerclay nanocomposites.…”

Polymer layered silicate nano-composites were prepared in melt by reactive extrusion (25:1 21 mm Rondol twinscrew compounding line) using poly(ethylene-co-propylene-co-ethylidenenorbornene) terpolymer (EPDM) as a matrx polymer, PP-g-MA and poly[(maleic anhydride-alt-1-octadecene)-g-PEO (poly(MA-alt-OD)-g-PEO) as functionalized polymer compatibilizer-internal plasticizer, octadecyl amine-montmorillonite (ODA-MMT) and dimethyldidodecyl ammonium -MMT (DMDA-MMT) as reactive and non-reactive nano-fillers, respectively. The formation of nano structural fragments, polymer blend composition-properties (thermal behavior and morphology) was studied using FTIR, XRD, TGA-DTG and DSC analysis methods. It was found that intercalation/exfoliation degree of EPDM macromolecules significantly depends on the origin and content of organoclays. Better results were obtained for nanocomposites prepared in the presence of reactive organo-filler (ODA-MMT) and PEO grafted alternating copolymer. The results of FTIR (chemical structure) and XRD (physical structure and exfoliation degree) analyses indicate that amidization of anhydride copolymer with alkyl amine groups of organo-filler and esterification of alternating copolymer with α -hydroxy-ω -methoxy-PEO occur in melt compounding in situ processing in the chosen extrusion conditions (barrel temperature: 120, 130, 140 and 145°C, twin-screw speed around 30-40 mrp). The glass-transition (Tg), melting (Tm) and recrystallization (Tc) temperatures strongly depend on the origin and content of organoclay and PEO-grafted copolymer-compatibilizer, respectively. Thermal behavior, crystallinity and thermostability of nanocomposites were significantly improved as compared with pristine EPDM terpolymer.

“…For example, when 5 phr organoclay was used to reinforce styrene-butadiene rubber (SBR), the tensile strength was improved from 2 to 3.7 MPa, while for polypropylene filled with 5 phr organoclay the tensile strength only increased from 32 to 35.8 MPa [7]. Different methods have been used to prepare rubber/layered silicate nanocomposites such as acrylonitrile-butadiene rubber (NBR) [8], ethylene-propylene-diene monomer (EPDM) [9], polyurethane (PU) rubber [10,11], natural rubber (NR) [12], butadiene rubber (BR) and SBR [13][14][15][16][17]. Generally, in situ polymerization, solution and melt intercalation are the preparation methods of rubber/clay nanocomposites, wherein organic modified layered silicate must be used.…”

“…However, considering that the latices are aqueous polymer dispersions and water is an excellent exfoliating agent for pristine clays, co-coagulating the mixture of rubber latex and layered silicate aqueous suspension (latex compounding method) is an easy method to prepare layered silicate/ rubber nanocomposites wherein pristine clay, i.e. sodium montmorillonite (Na-MMT), is used instead of organic clay [13][14][18][19].…”

Carboxylated styrene-butadiene rubber (XSBR)/clay nanocomposites were prepared by mixing the XSBR latex with aqueous clay dispersion and cocoagulating the mixture. TEM and XRD were applied to characterize the structure of nanocomposites. Fully exfoliated structure was observed for the nanocomposites containing equal to or less than 10 phr (weight parts per hundred) clay. With increasing the clay content to 20 phr, both non-exfoliated (stacked layers) and exfoliated structures can be observed simultaneously in the nanocomposites. The results of mechanical tests on the vulcanized clay-free XSBR and XSBR/clay nanocomposites showed that the nanocomposites present better mechanical properties than clay-free XSBR vulcanizate. Furthermore, modulus, tensile strength, tensile strain at break and hardness (shore A) increased with increasing the clay content, indicating the nanoreinforcement effect of clay on the mechanical properties of XSBR/ clay nanocomposites.
