Abstract: A multi-stable electroresponsive smart window and preparation method thereof are disclosed. The multi-stable electroresponsive smart window comprises a first light transmitting conductive substrate, a parallel orientation layer, a positive polymer stabilized cholesteric texture layer, a positive cholesteric texture layer and a second light transmitting conductive substrate disposed in stack successively. The multi-stable electroresponsive smart window of the present disclosure can realize a diversified light transmission state such as colored and transparent state, colored and blur state, colorless and blur state, and colorless and transparent state by changing the magnitude of the access voltage, thereby satisfying the various demands in people's work and life. In addition, the multi-stable electroresponsive smart window of the present disclosure has the characteristics of simple production, rich patterns, energy saving and environmental protection, which has good application prospects in the fields of window glass, home glass window and glass curtain wall, and the like.

Abstract: A liquid crystal mixture and a temperature-responsive infrared reflection device made by using the liquid crystal mixture containing potassium laurate. Infrared light can pass through the device within a non-working temperature range, and a chiral dopant enables potassium laurate to form a cholesteric phase within a working temperature range. The birefringence value of the potassium laurate gradually increases with the increase of temperature between 12.5° C. and 26° C., so that the infrared reflection bandwidth of the device constantly increases. The birefringence value of the potassium laurate gradually decreases with the increase of temperature between 26° C. and 54.5° C., so that the infrared reflection bandwidth of the device constantly decreases. The infrared reflection bandwidth of the infrared reflection device can vary with temperature by adjusting the proportions of the ingredients of the liquid crystal mixture containing potassium laurate.

Abstract: Disclosed is an electrofluidic support plate and a method for preparing the same, and an electrofluidic device comprising the support plate. The method comprises the following steps of: providing a substrate which has a surface provided with an electrode layer; arranging a first amorphous fluoropolymer layer on the surface of the substrate, and carrying out hydrophilic modification on a surface of the amorphous fluoropolymer layer; arranging pixel walls on the amorphous fluoropolymer layer after hydrophilic modification; arranging a second amorphous fluoropolymer layer which is a hydrophobic layer; the second amorphous fluoropolymer layer covering all surfaces of the pixel walls and a groove area encircled by the pixel walls; filling the groove area encircled by the pixel walls with a protective material; removing the second amorphous fluoropolymer layer not covered by the protective material and on a top of the pixel walls; and removing the protective material.
