Poly optical microscopy image

Fig. 2 Optical microscopy image of a small section of a poly(ethylene oxide) (PEO) droplet dispersion sample, see text (1000-mm wide) obtained at Tc = - 2.6 °C. Amorphous droplets appear dark and semicrystalline droplets appear white under nearly crossed polarizers. The plot shows the fraction of crystallized droplets as a function of temperature upon cooling (0.4 °C min-1) for homogeneous nucleation.

Polarized optical microscopy (POM) was performed to confirm the transition temperatures obtained by DSC studies and to find out the type of mesophases present in the synthesized polymers, the crystal phase to nematic phase transition temperature (Cr-N), and nematic phase to isotropic phase (N-1) temperature. It was found that the transition temperatures of the polymers are almost the same as those obtained in DSC. The POM results revealed that the poly(azomethine esters) 3(b-d) exhibit nematic liquid crystal phases and the images were shown in Fig. 12.5.
