Figure 3: SEM micrographs showing the effect of binary solvent systems on web structure and CA electrospun fibre morphology. Mag 630x–1260x-electrospinning solvents: (a) acetone : methanol (3 : 2); (b) acetone : methanol (4 : 1); (c) chloroform : methanol (4 : 1); (d) ribbon-like structure in an electrospun CA fibre produced from the Chloroform : methanol (4 : 1) solvent.
