摘要：

A series of TiO2 nanorod arrays were obtained by hydrothermal reaction, then the morphologies were characterized and analysed. In the light polymerization condition, different morphologies of TiO2 nanorod arrays and chiral nematic liquid crystalline (N*-LCs) media were combined to prepare broad-band reflectors. By adjusting the length and interval size of the TiO2 nanorod arrays, the reflection spectra and the positions of the reflected spectrum and the reflected bandwidth can be controlled accordingly. As a result, the effect of polymerization temperatures and morphologies of TiO2 nanorod arrays on the broad-band reflection in the N*-LC composite system has been investigated. Potential applications of the composite were related to brightness enhancement films, bandwidth-controllable reflective polarizers and near-infrared light blocking films. [GRAPHICS] .
