Fig. 1. POMs of the normal nematic LCE (I), modified nematic LCE (II), normal nematic G–LCE (III) and modified nematic G–LCE (IV). Inserted cross arrows illustrate the polarization directions of the two polarizers. (a) The stretch direction of the LCE material is parallel to the vertical polarization direction. (b) The stretch direction of the LCE material is parallel to the horizontal polarization direction. (c) The angle between the stretch direction of the LCE material and the polarization direction of either polarizer is −45°. (d) The angle between the stretch direction of the LCE material and the polarization direction of either polarizer is 45°.
