Polymer stabilized liquid crystal (PSLC) devices can be used as smart privacy windows that switch between transparent and opaque states. The polyimide alignment layer of a PSLC device is usually obtained by the treatment polyamide acid (PAA) with temperatures over 200 °C. This hinders fabrication on flexible substrates, which melt at these high temperatures. In this work, using lower temperature compatible most demonstrated. It was found PAA 150 °C could generate same for crystals. Based...
