WebNov 2, 2024 · The growth rates of Type-1 and Type-2, respectively, are compared as shown in Figure 4. Results show that there is no significant difference in the spherulites growth rates between them. The initiation times (or incubation of first traces of nuclei) for Type-1 and Type-2 are dramatically different.
