Enhancing Polyamide ۶ and ۶.۶ Properties with Nanofillers: A Study on Graphene, CNTs, Carbon Fibers, and Titanium Dioxide- Short Review

Polyamide ۶ (PA۶) and polyamide ۶.۶ (PA۶۶) are essential engineering polymers, valued for their strong mechanical properties, thermal stability, and durability. Recent developments in polymer nanocomposites have shown that adding nanofillers like graphene, carbon nanotubes (CNTs), carbon fibers, and titanium dioxide (TiO₂) can significantly improve these polymers. Graphene, in particular, stands out due to its remarkable ability to enhance mechanical, electrical, and thermal properties, even at very low concentrations. As a result, graphene-polyamide (G-PA) nanocomposites have attracted a lot of attention for their potential use in high-performance applications. In the case of PA۶۶, combining carbon fibers with acyl chloride-functionalized graphene oxide (AGO) and CNTs has led to notable improvements in tensile strength, shear strength, and stiffness. These enhancements come from the strong interfacial bonding between the materials, better dispersion of fillers, and efficient load transfer. Furthermore, integrating TiO₂ and graphene oxide (GO) into polymer membranes has shown great promise in separation processes, improving key factors like hydrophilicity, salt rejection, and oil rejection. These advancements highlight the potential of nanocomposites to create versatile, high-performing materials for various industrial uses.
