| Summary: | 碩士 === 國立交通大學 === 光電系統研究所 === 105 === This work discusses the phase separation of silica nanoparticle-doped liquid crystal (LC) mixtures. We find that the phase separation of the LC mixtures involves the nucleation and growth of nematic domains followed by the aggregation of silica nanoparticles. The final morphology of LC mixtures after phase separation depends on the concentration and surface properties of silica nanoparticles. The temperature-dependent dielectric permittivity at 1 kHz and 10 Hz can reveal the clear point temperature and the onset of the aggregation of silica nanoparticles in LC mixtures, respectively.
