| Wu and Liao examined the effect of thermal history and filler concentration on the crystal structure of polyamide 6 nanocomposites formed by in situ polymerization using synthetic saponite and natural montmorillonite [208, 209]. Similar crystalline behavior was observed for the pure and nanocomposite materials when samples were slowly or rapidly cooled from the melt; however, nanocomposites containing a low concentration of saponite, i.e. 2.5 wt. %, favored the formation of the α-form regardless of the cooling conditions, whereas by increasing silica content γ-form is more dominant (Figure 4.5). Annealing studies showed that higher amounts of γ were present in the nanocomposite than in pure polyamide 6 after annealing at high temperatures, except at low saponite contents.

Wu and Liao examined the effect of thermal history and filler concentration on the crystal structure of nylon 6 nanocomposites formed by in situ polymerization using synthetic saponite and natural montmorillonite [53, 54]. Similar crystalline behavior was observed for the pure and nanocomposite materials when samples were slowly or rapidly cooled from the melt; however, nanocomposites containing a low concentration of saponite, i.e., 2.5 weight %, favored the formation of the α-form regardless of the cooling conditions. Annealing studies showed that higher amounts of γ were present in the nanocomposite than in pure nylon 6 after annealing at high temperatures, except at low saponite contents.
