From: Well-ordered polymer nano-fibers with self-cleaning property by disturbing crystallization process
The mechanism for well-ordered polymer nano-fibers by external macroscopic force. The sketch map of macroscopic and microscopic forces on polymer chains during natural crystallization under protection of different atmospheres (a, b): FS, a stretching force generated from natural crystallization of macromolecular chains; Fblow, a microscopic force macromolecular chains derived from macroscopic H2 gas flow.
