What is Electrospinning fabrication of partially crystalline bisphenol A polycarbonate nanofibers: The effects of molecular motion and conformation in solutions about?

Partially crystalline bisphenol A polycarbonate (BPAPC) nanofibers were successfully fabricated using a combination of a centrifugal field (1800 rpm) and an electrostatic field (25 kV). The BPAPC solution properties are key factors for adequately electrospinning the partially crystalline BPAPC nanofibers. The correlation times (s c ) of methyl (s c 1⁄4 9.3 ns) and of benzene-ring (s c 1⁄4 15.3 and 15.8 ns) motions in the 14 wt.% BPAPC/THF solution were longer than in CH 2 Cl 2 and CHCl 3 , as determined by NMR. The distribution-peak maximum of the hydrodynamic radius of BPAPC in the 14 wt.% THF solution (R h 1⁄4 15 A) was higher than in CH 2 Cl 2 (R h 1⁄4 9.2 A) and CHCl 3 (R h 1⁄4 7.9 A), as evidenced by DLS data. We conclude that the BPAPC assumed a denser, more worm-like chain conformation in THF solvation.
