Rubber/Ca-montmorillonite (Ca-MMT) nanocomposites with exfoliated Ca-MMT layers was prepared by a new preparation method named masterbatch method, in which the masterbatch was prepared by co-coagulating nature rubber latex and bis [3-triethoxysilylpropyl-] tetrasulfide (TESPT) modified Ca-MMT aqueous suspension and then the masterbatch accompanied with carbon black (N220) were used in the system of SBR and ENR. The properties of TESPT in-situ modified Ca-MMT were investigated by Fourier-transform infrared spectroscopy and thermogravimetric analysis. The results showed that the TESPT has reacted with the surface groups of Ca-MMT. The dispersion of the Ca-MMT in masterbatch and vulcanized sample was characterized by X-ray diffraction. The results showed that in the masterbatch an exfoliated structure was obtained and in the vulcanized sample a coexistence of intercalated-exfoliated structure was obtained. The influence of the Ca-MMT loading on the structure and properties of the nanocomposites were studied. It was found that the incorporation of Ca-MMT hindered the vulcanization, improved mechanical properties, thermal properties and aging resistance properties. The dynamic mechanical analysis results showed a decrease of tanδ max when the Ca-MMT is added.

The influence of additives of nanofillers (NF) containing nanoparticles of copper oxides stabilized by a polymer matrix of high-pressure polyethylene (PE) obtained by the mechanochemical method on the structure and properties features of metal-containing nanocomposites based on isotactic polypropylene (PP) and butadiene-nitrile rubber (BNK) is studied by X-ray phase (XRD) and differential thermal analyses(DTA). The improvement of strength, deformation and rheological parameters, as well as thermal-oxidative stability of the obtained nanocomposites was revealed, which, apparently, is associated with the synergistic effect of interfacial interaction of copper-containing nanoparticles in the PE matrix with the components of the PP/BNK polymer composition. It is shown that nanocomposites based on PP/BNK/NF can be processed both by pressing method and by injection molding and extrusion methods, which expands the scope of its application.

Results of the studies of technology, structural features and properties of polymer/clay nanocomposites (n-PCM) prepared by melt compounding of thermoplastic polymers are systematized. Special attention is given to the analysis of the effect of nanoclays modification with surfactants on properties of nanocomposites and preparation features of nanomaterials based on polar, non-polar thermoplastics and polymer blends. Effect of technological factors and special compounding regimes in the technology of n-PCM with advanced technical characteristics is considered. Results of the original studies of the structure and properties of the hybrid composites, filled by high modulus fibers in addition to nanoclays, are presented.
