The structure development proceeds in two steps. A very fast evolution of PEO crystals from the melt starts to crystallize in disordered NIF lamellae with thick amorphous interlayers and with a lower density of crystalline phase. In the second step, the structure of crystalline phase gradually improves and NIF lamellae recrystallize to more stable structures.
