Abstract
Recently, thermal-response hydrogel smart window is widely studied because of its high luminous transmittance (τlum) and high solar modulation ability (Δτsol). However, its liquid state is undesirable for window applications. Wood has strong mechanical strength and low thermal conductivity. Due to the unique features of the thermal-response hydrogel and wood, a thermochromic hydrogel wood composite (HWC) that can smartly regulate solar irradiation is proposed by impregnating a thermal-response hydrogel into delignified wood. The novel HWC demonstrates advanced optical properties (i.e. τlum = 83% and 40% at the cold transparent and hot opaque states & Δτsol = 38%) and low transition temperature (i.e. Tc = 23 ºC). Moreover, the HWC is highly flexible and easily fitted into existing windows frames. Overall, the HWC with its impressive features shows great promise for energy-efficient material for smart windows in buildings.
