The non-isothermal crystallization behaviors of pure PA6, PA6/unfunctionalized silica (PA6S) and PA6/functionalized silica (PA6FS) hybrid materials were investigated by differential scanning calorimetry (DSC). Two methods, namely, the Avrami and the Mo, were applied to describe the crystallization process of these three materials. DSC results showed that the crystallization rates of PA6FS is faster than that of pure PA6 and PA6S at the same cooling rate, the nano-silica particles functionalized by GPS in hybrid material acted as more effective nucleation agents, and the crystallization rates of all these samples increased with the cooling rate increasing. XRD results indicated that the addition of functionalized nano-silica particles favored the formation of the γ crystalline form.
