scale are presented in Figure 5 together with a TEM micrograph of each hydrogel at different agitation conditions.
Figure 5. CMF/CNF diameter distribution and TEM images at different stirring speeds: ( a )R-CNF diameter distribution; ( a1 ) 3 s − 1 ; ( a2 ) 70 s − 1 ; ( a3 ) 125 s − 1 ; ( a4 ) 500 s − 1 ; ( a5 ) 2500 s − 1 ; ( b ) R-CMF diameter distribution; ( b1 ) 50 s − 1 ; ( b2 ) 500 s − 1 ; ( b3 ) 900 s − 1 ; ( b4 ) 2500 s − 1 . The differences between both hydrogels are related to the pretreatments used to obtain the hydrogels, which produce the variation of fiber size. R-CNF has a higher number of
