Abstract

Partially crystalline bisphenol A polycarbonate (BPAPC) nanofibers were successfully fabricated using a combination of a centrifugal field (1800rpm) and an electrostatic field (25kV). The BPAPC solution properties are key factors for adequately electrospinning the partially crystalline BPAPC nanofibers. The correlation times (τ_c) of methyl (τ_c=9.3 ns) and of benzene-ring (τ_c=15.3 and 15.8 ns) motions in the 14wt.% BPAPC/THF solution were longer than in CH₂Cl₂ and CHCl₃, as determined by NMR. The distribution-peak maximum of the hydrodynamic radius of BPAPC in the 14wt.% THF solution (R_h=15Å) was higher than in CH₂Cl₂ (R_h=9.2Å) and CHCl₃ (R_h=7.9Å), as evidenced by DLS data. We conclude that the BPAPC assumed a denser, more worm-like chain conformation in THF solvation.
