Abstract: | Electrospinning is a versatile process used to prepare micro- and nano- sized fibers from various polymer solution. Here,
we dealt with the variation in the morphology of nylon 6 electrospun nanofibers and their polymorphism depending on the type
and physical state of the collectors. SEM study showed that the fiber diameter was increased from 80 to 103 nm while it was
collected in water bath. Similarly the fiber diameter and bonding was increased 103 to 115 nm with the temperature whereas
it was linearly decreased 103 to 90 nm with the conductivity of the water bath. Spectroscopic analysis (FT-Raman, FT-IR) showed
that the polymorphism of nylon 6 depended on the types of collector (aluminum sheet and water bath). Nylon 6 electrospun nanofibers
display theγ-phase while collected in aluminum sheet andα-phase while collection in water bath. The extent of transformation fromγ- toα-phase was linearly increased with temperature and conductivity of the water bath. |
