Electro-optical response of thiol-ene based PDLC

PDLC with micrometer or submicrometer sized droplets have been demonstrated using acrylate syrup as polymer precursor. In this paper the ability of thiol-ene monomere to lead to such PDLC is investigated. Electro-optic response of bulk composite material is measured by an interferometric setup and compared to theoretical model. A morphological study has shown a specific response of submicrometer PDLC. UV laser (355 nm) has been used to record gratings. The weakness of diffractive efficiency seems to show an intrinsic limitation of nanosized PDLC for low spatial frequencies.
