Figure 6
SEM images using, for each figure, the backscattered electron technique (left) and the secondary electron technique (right) for (a) the control electrospun PLA nanofibres without any particles (0 wt% of Bi2O3); (b) 28 wt% Bi2O3 of electrospun n-Bi2O3/PLA nanofibres; (c) 28 wt% Bi2O3 of electrospun m-Bi2O3/PLA nanofibres; (d) 38 wt% Bi2O3 of electrospun n-Bi2O3/PLA nanofibres; and (e) 38 wt% Bi2O3 of electrospun m-Bi2O3/PLA nanofibres. |
