摘要：

Barium titanate stabilized by gamma-cyclodextrin nanoparticles were prepared by using a microwave reactor equipped with ultrasonic nozzle mixing at 240 degrees C in a tetraethylene glycol solution of barium ethoxide and titanium ethoxide in the presence of gamma-cyclodextrin. Particles in gamma-cyclodextrin-stabilized BaTiO3 nanoparticles had an average diameter of 2.1nm and mainly distributed within the range of about 1 to 4nm. The gamma-cyclodextrin-stabilized BaTiO3 nanoparticles were mixed with 4-cyano-4 '-pentylbiphenyl at room temperature resulting in a liquid crystal sol of 4-cyano-4 '-pentylbiphenyl. The response time of liquid crystal devices in the presence of gamma-cyclodextrin-stabilized BaTiO3 nanoparticles was faster than that in the absence.
