Composite films with an array of needle-like TiO2 particles in urethane resin matrix were fabricated by applying alternating current (AC) bias. The resulting composite films showed angular dependence of transmittance in the visible-near infrared (NIR) wavelength range. The resulting composite films assumed to be applied to smart windows and privacy films.
