Fabrication and Evaluation of Arrayed Needle-Like TiO2 Particle – Transparent Resin Composite Films
Needle-like TiO2-resin composite films were fabricated using needle-like TiO2 particle filler and urethane matrix. The needle-like TiO2 particles in the composite film were arrayed completely under the fabrication condition of applying AC bias of 10 volt with 0.1 Hz for 4 hr, and the transmittance of the resulting composite film showed angularly dependence. The needle-like TiO2 particles in the composite were oriented quickly by a larger applying bias. Furthermore, increase of the mixing ratio of TiO2 particles in the composite film caused increasing an angularly dependence of the transmittance of the composites.
