| Abstract: | Polarized infrared spectroscopy and temperature dependent FTIR spectroscopy were used to study molecular orientation of different polymer dispersed liquid crystal films. Line array detection technology was used to study the interface component between the polymer and liquid crystal. Measurements of absorbance changes of the representative IR bands as a function of the polarization angle show that the phase transition with temperature increasing was gradually. The distribution figure of the interface compone... |
