In order to effectively reduce the turn-on voltage of the liquid crystal device and low power consumption characteristics. Gold nanoparticles with an average particle diameter of about 5 nm were prepared by using polyhedral oligomeric silsesquioxanes (POSS) as the modification ligand and NaBH₄ as the reductant to reduce the chloroauric acid. Gold nanoparticles were doped into nematic liquid crystal 4-n-pentyl-4'-cyanobiphenyl (5CB) with different mass fractions to study its effect on the viscosity, the threshold voltage and the phase transition temperature. The results show that the viscosity and the threshold voltage of 5CB are decreased by doping with POSS modified gold nanoparticles. Moreover, the phase transition temperature range of 5CB is broadened by addition of the gold nanoparticles.
