Figure 3.

IR spectra of (a) pure PVP (black); M (red); CL (blue) and LCE-PVP fibers polymerized at 55 ${}^{\circ }$C (green continuous) and (b) pure PLA (black); M (red); CL (blue); LCE-PLA fibers polymerized at 55 ${}^{\circ }$C (green continuous) and CL-PLA fibers polymerized at room temperature (green dashed). The dashed line highlight the regimes of the C=C stretch (1635 cm${}^{-1}$) and C=H bend (810 cm${}^{-1}$) vibrations, respectively.
