The mechanism for polymer nano-papules or nano-wires by internal microscopic force. The sketch map for mechanism of nano-papules, nano-segments, and nano-wires structures by internal microscopic force interferences (FS and FT) under uniform and non-uniform cooling conditions (a, b): FS, a stretching force generated from natural crystallization of macromolecular chains; FT, a new tensile force derived from the shrinkage of surrounding macromolecular chains when the temperature dramatically decreased.
