The invention discloses a continuous color-changing intelligent energy-saving window prepared through
laser-induced forward transfer, which comprises a first matrix layer, a composite functional layer and a second matrix layer which are sequentially stacked, and the composite functional layer comprises a three-dimensional
surface plasmon structure layer and a thermochromic
liquid crystal layer, the three-dimensional
surface plasmon structure layer is prepared through a
laser-induced forward transfer process, and a patterned three-dimensional micro-nano structure is formed on the first substrate layer; the thermochromic
liquid crystal layer comprises liquid crystals and a chiral agent, and the reflection
wavelength of the thermochromic
liquid crystal layer is continuously adjustable in the whole visible
light wave band along with temperature changes. Energy saving is achieved through strong absorption of the three-dimensional
surface plasmon structure layer on visible light and
infrared bands in ambient light, and the
photothermal effect of the three-dimensional surface
plasmon structure layer is used for driving the thermochromic liquid
crystal layer to generate continuous and reversible
color changes of full visible light bands; meanwhile, the structural layer is black or dark due to strong absorption, and the brightness of the reflection color of the liquid
crystal layer is remarkably enhanced.
