Selective Localization

Selective localization of carbon nanotubes (CNTs) at the interface of immiscible polymer blend was achieved by the method that poly(styrene-co-maleic anhydride) (SMA) was first reacted with CNTs, and then blended with nylon6/polystyrene (PA6/PS). In the PA6/PS blends, CNTs was localized in PA6 phase and the percolation threshold was 2wt%. However, for the PA6/PS/(SMA- CNTs) composites, TEM results showed that most of CNTs were selectively localized in matrix, but some of tubes were induced by SMA to disperse at the interface. The localization of CNTs at the interface caused the percolation threshold of PA6/PS/(SMA- CNTs) was only 0.33 wt%, which is much lower than that of PA6/PS/ CNTs.

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.
