“…There have been numerous approaches to manipulate and improve HPDLC performance parameters such as diffraction efficiency, contrast, switching speed and voltages. These include photocurable acrylate systems (1,3,6,12,(14)(15)(16)(17)(18), photopolymerisable thiol-ene based polymers (9)(10)(11)(19)(20), non-reactive surfactant-like molecules (21)(22)(23), conductive polymer molecules (8,24), and so on (25)(26)(27)(28). In most visibly recorded HPDLCs to date, a number of additives are typically required (23).…”
