摘要: Diffraction efficiency and morphology of holographic gratings were improved by combining ring-opening polymerizable epoxides with radical conventional acrylate systems. By adding epoxide materials, the grating spacings increased when compared case where only was used. The effects especially notable for cyclohexane oxide derivatives. diffraction highest, nanoscale phase-separated liquid crystal domains most clearly formed using siloxane-containing group, due to their incompatibility fast curing.
