“…The thiol‐ene click reaction is the hydrothiolation of a C═C bond, defined by Kolb et al, and has often conducted via the dissociation of a photoinitiator into a radical species . Moreover, the thiol‐ene click reaction has simplicity, robustness, and fast reaction speed in the field of polymer and materials chemistry . The reactivity in the radical thiol‐ene reaction can vary considerably depending on the chemical structure of the ‐ene and thiol components and the ‐ene reactivity with alkyl 3‐mercaptopropionates, alkyl thioglycolates, and alkyl thiols under radical conditions, following the order: vinyl ether > allyl ether > acrylate .…”

In this work, the thiol‐ene click reaction is employed to fabricate polymer‐dispersed liquid crystal (PDLC) films by photoinitiated polymerization. The PDLC films are prepared by systematic variation of key conditions: variety and content of ‐ene monomer, liquid crystal (LC) content, curing time, and curing light intensity. We find that both the morphologies and electro‐optic properties of these films are adjustable. When increasing the length of alkyl main chain of ‐ene monomers, the driving voltages reduce, but in turn, the contrast ratio decreases. Increasing ‐ene monomer content raises the driving voltages as well as the response time, and the increase of LC content lowers the driving voltages but has a negative effect on the contrast ratio. The changes to the curing conditions (both curing time and UV light intensity) can be used to modify the driving voltages, response time, and contrast ratios of PDLC films. These comparative studies will elucidate new insights in commercial applications of intelligent PDLC films.
