Figure 2.
Electrospinning of 4 wt% HMWH (f = 3.9): 1 wt% PEG (Mn =2 000 g/mol, f = 2): 1 wt% PEO. (a)MPT measurements of the gelation reaction, the solid black markers indicate the time periods when continuous electrospinning is observed and the dashed line indicates the sol-gel transition. (b) A brightfield image of the fluid jet, scalebar is 0.25 mm, and (c) an SEM image of the fibers.
