The production of ‘polymer nanocomposites’ has recently gained considerable attention from both the academic and industrial community, especially in the area of nanoscience. This is mainly due to their enhanced improvements in physico-mechanical, thermal and barrier properties compared to micro and more conventional composites. Their nanoscale dimensions, biodegradable character, cost-effectiveness and sustainability have constituted a stimulus for this increasing interest. Currently there is no limit to the possibility of applications. However, despite all this progress, it is still difficult to achieve uniform dispersion between the filler and the matrix, as agglomerations form far too easily and the production of polymer nanocomposites with high mechanical and thermal properties is still limited. The authors of this proposed book, are of the opinion, that with the increase in scientific publications and the rapid progress in processing possibilities to produce nanocomposites based on various nanoscale fillers (silica/clay), a book that collects all of these scientific findings in one place would be timely and of great interest to both students and scientific researchers, who are concerned with the production, and application of nanocomposites as new innovative materials. The authors aim is to present the latest research findings on the fabrication, properties and applications of nanofillers as reinforcement in polymer nanocomposites. Particular emphasis will be placed on the introduction of various nanofillers (silica/clay) into different elastomeric polymer matrices that will enhance the properties of these materials and their applications. The book will provide an up-to-date review of major innovations in the field and act as a reference for future research in materials science and engineering, which is highly topical due to the demand to produce more sustainable and eco-friendly innovative advanced materials from elastomeric polymers. Emphasis on silica/clay as outstanding reinforcing potential in elastomeric polymer matrices Up-to-date on the most relevant innovations in the field of silica/clay nanocomposites and their extensive applications in advanced material science Establishes the most suitable fabrication methods, properties and applications as a solid foundation in materials science and engineering disciplines Includes the incorporation of dual nanofillers that significantly improve the properties of nanocomposites

"Nanocomposites comprising either pristine or organically modified layered silicates or silica were synthesized in-situ via the interfacial polycondensation of polyamide-6,6; the silica was also generated in-situ via sol-gel reactions during the nylon polymerization. The thermo-mechanical properties of these nanocomposites were evaluated by Thermogravimetric Analysis (TGA) and Dynamic Mechanical Analysis (DMA). In addition, Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), Wide Angle X-Ray Diffraction (WAXD), and Energy Dispersive Spectroscopy (EDS) measurements were used to identify the functional groups, to understand the effect of the filler on the phase transition behavior, to evaluate the basal spacing of clay layers in the case of layered silicate nanocomposites, and to observe the presence and dispersion of chemical elements, respectively. The evaluation of reaction variables via statistically designed experiments revealed that the concentration ratio of hexamethylenediamine to adipoyl chloride and the type of mixing imparted to the reaction mixture are important variables affecting molecular weight. It was found that the final clay content in the nanocomposites can be adjusted by changing the concentration of the clay selectively dispersed in one of the reagent phases. The synthesis of dispersed layered silicate nanocomposites required producing a colloidal dispersion of the clay prior to mixing it with the reactive monomers. Stirring was found to be critical in terms of keeping clay dispersed during the polymerization. Better dispersion of the layered silicates in the nanocomposites was achieved with longer mixing times in stirred reactors. The presence of surfactants in the clay galleries resulted in the formation of imperfect (lower-melting) nylon crystals from the melt. Enhancement in thermal stability and mechanical stiffness was observed with the addition of layered silicates to the polymerized nylon. Silica particles could be co-generated in-situ using sol-gel chemistry at reaction times or residence times varying from 15 sec to 2 min. Variation in the molar ratio of water to tetraethoxysilane (TEOS), designated by r, results in different silica morphology, ranging from predominantly spherical particles at r ratios of 10 to 20 to agglomerates or open network structures at r ratios from 100 to 890. It was found that generation of silica in the reaction systems using smaller quantities of water gave rise to low molecular weight polyamide chains and also altered their crystallization and melting behavior. Imperfect nylon crystals in these nanocomposites gave rise to three melting peaks associated with different crystal structures. Such effects of filler on phase transition behavior diminished when the polymer molecular weight increased at higher r ratios. Hybrids incorporating chemical connectivity between the inorganic parts (generated from sol-gel reactions) and the polyamide chains generated using a coupling agent exhibited differences in crystalline structure depending upon the extent of reaction. Hybrids were found to have superior mechanical stiffness as compared to unfunctionalized silica nanocomposites, which is attributed to the chemical bonding between the polymer chains and the inorganic structure of the hybrids. Variations in the nylon molecular weight observed with addition of either coupling agent or layered silicate co-reinforcement are attributed to changes in the mass transfer of the polycondensation reagents to the reaction zone. The especially dramatic changes in molecular weight with the addition of the (3-Aminopropyl) triethoxysilane (APTES) coupling agent are attributed to its lower solubility in water vs. TEOS. The dispersion of sodium montmorillonite (NaMMT) layered silicate in the nanocomposites could be improved by the in-situ co-generation of silica in unstirred reactors. Nanocomposite mass is rendered more stable (less fugitive) at elevated temperature in the presence of such hybrid structures as compared to neat PA66."--abstract.
