A roll-to-roll process for multi-responsive soft-matter composite films containing Cs x WO 3 nanorods for energy-efficient smart window applications.

This work provides a roll-to-roll processed flexible multi-responsive smart film containing tungsten bronze nanorods and a phase-separated liquid crystal-polymer composite, which can reversibly control the passage of visible light in response to temperature, an electric field and near infrared light, and also screen the heat rays from 800 nm to 2500 nm.
