Abstract
Abstract Transmission gratings of holographic polymer dispersed liquid crystals (HPDLCs) have been designed and fabricated based on partial fluorination of the polymer matrix using three types of fluorinated monomers carrying different numbers of fluorine atoms and structures, viz. 2-(perfluoroalkyl)ethyl methacrylate (PFEMA), 2,2,2-trifluoroethyl methacrylate (TFEMA), and 2,2,2-trifluoroethyl acrylate (TFEA). Addition of fluorinated monomer gave long saturation time, increased off state diffraction efficiency, small anchoring strength and driving voltage. Anchoring strength and driving voltage of methacrylate monomers (PFEMA and TFEMA) were lower than that of TFEA, implying that the fluorine segments of these monomers are preferentially exposed to the interfaces. HPDLC film having low driving voltage and response time of below 10 ms has been fabricated with 20 wt % PFEMA at 40 wt % LC.
