The modified coaxial electrospinning, in which only organic solvents or their mixtures are utilized as sheath working fluids, is a useful way for manipulating nanofibers' diameters. In this study, with a co-dissolving solution consisting of poly( -caprolactone) (PCL) and poly(trimethylene carbonate) (PTMC) at a concentration of 12 wt% in a mixture of dichloromethane (DCM)/N,N-dimethylformamide (DMF) as the core fluid, a series of solvent mixtures with a varied compositions of them were exploited as the sheath fluids to control the sizes of electrospun PCL/PTMC nanofibers. The scanning electron microscopic results demonstrated that the nanofibers' diameter (D) had a fine relationship with the DMF volume ratio (Vr) in the sheath fluids as D=162Vr-0.61 (R2=0.9922). This job opens a new way for conducting the modified coaxial processes and for adjusting the sizes of fibers intentionally.
