The effects of epoxy resin addition to a standard acrylate-based holographic polymer dispersed liquid-crystal mixture are investigated. Different resin concentrations are used and we show how the presence of the resin results in transmission gratings characterized by negligible scattering, polarization independent behaviour and lower switching voltages. These experimental results are explained by means of morphological scanning electron microscopy analyses.

Abstract
The effects of epoxy resin addition to a standard acrylate-based holographic polymer dispersed liquid-crystal mixture are investigated. Different resin concentrations are used and we show how the presence of the resin results in transmission gratings characterized by negligible scattering, polarization independent behaviour and lower switching voltages. These experimental results are explained by means of morphological scanning electron microscopy analyses.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
