The Generation And Thermo Mechanical Characterization Of Advanced Polyamide 6 6 Nanocomposites Using Interfacial Polycondensation by Zehra Sibel Kalkan

Original Title: The Generation And Thermo Mechanical Characterization Of Advanced Polyamide 6 6 Nanocomposites Using Interfacial Polycondensation

"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.
