A simple transition: An evolution from a straight internal helical to hierarchical helical (HH) mesostructure with both internal and external helices or screwlike and concentric circular (CC) mesostructures is successfully observed. The HH structures with both internal and external helices are formed during the helix–coil transition process (region I; see picture). Structural mutation occurs in the restricted region (II), thus resulting in the complicated screwlike and CC mesostructures.
