CNFs were characterized in terms of particle diameter (D), length
(L), and aspect ratio (L/D). Table 1 shows that CTand ETaffected length
themost.Nanofibers isolatedfromthebananapeelhaddiameters and lengths of 10.9 and 454.9 nm (CT) and 7.6 and 2889.7 nm (ET),
respectively. The aspect ratio ranged from about 42.7 (CT) to 353.9
(ET). Both results were satisfactory; however, ET yielded longer
nanofibers and higher aspect ratio, and the values lay in the range that
made them potentially useful as reinforcing agents in composites.
George et al. (2011) stated that high aspect ratio should favor tension
transfer in the nanofiberematrix interface.
