Comparative Analysis of the Thermal Behavior of Nylon-6 Composites Reinforced with Functionalized and Non-Functionalized Silica
Abstract: This work presents a systematic evaluation of surface-functionalized silica as reinforcing filler in Nylon-6 composites. Both non-functionalized and 3-aminopropyltrimethoxysilane (APTMS at loadings of 1-4 wt%) functionalized silica particles were incorporated into a Nylon-6 matrix through melt compounding. The comparative effects of both fillers on crystallization and thermal behaviour were analysed using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The incorporation of silica resulted in a slight enhancement in crystallization behavior, with the onset crystallization temperature (Tc, onset) exceeding 196 ?C for both non-functionalized and APTMS-functionalized silica filled composites. These results indicate that both fillers function as effective nucleating agents, facilitating earlier crystallization of the polymer matrix. All Nylon-6/APTMS-functionalized silica composites show increased char yields, ranging from 1.52% to 2.48%. Nylon-6/APTMS-functionalized silica composite (NS4) shows the highest char yield (2.48%), suggesting a stronger protective effect at higher filler content. The present study demonstrates the potential of APTMS-functionalized silica for the development of high-performance Nylon-6 composites intended for advanced engineering applications.
