FTIR analysis was performed on the hybrid material after its drying (Fig. 1).
Additionally, the existence of symmetric and asymmetric extension vibrations of CH2 and CH3 of the propylo chains at 2836 cm-1 and 2942 cm-1 suggests the presence of PEI in the network [19].

Abstract.
First, the cold-rolled foil had a strong {110} texture, as shown in Fig. 1(a).
Surprisingly, the texture returned to the same {110} texture as the cold rolled one after the grain growth at higher temperatures, typically 1273K (Fig. 1(c)).
